In the subject of cryptography, what policy or organizational challenges might impede or prevent the deployment of a worldwide universal Public-Key Infrastructure? Solution Below challenges may present the deployment of Universal PKI : 1. Token Logistics: There are many advantages of implementing PKI on a hardware token, such as a smart card. These include security, portability and ease of use to add other user specific applications and visual information. However, the logistics of managing security tokens requires a considerable effort and cost to a Public-Key Infrastructure implementation. 2. Network Issues: The implementation of PKI will surely add to the network load. The potential additional traffic that should be considered are: i. Certificate issuance ii. Email Usage iii. Directory Replication. 3. Network Issues - Encryption: Usually the organisations implement anti-virus software and on regular basis perform inspection on servers at the perimeter of their networks. Some organizations has security policies that rejects or quarantines encrypted traffic. To provide user-to-user confidentiality, the messages will traverse networks with their payload hidden from inspection by virus and content checking. Possible solutions include: · Performing virus & content checking at the client machine. · Storing user confidentiality private keys on a secure key server. · Co-encrypting messages to a Gateway which then decrypts and checks the message before it is delivered. 4. Email Address in Certificate: Usually employees change their email addresses more frequently than the certificate. Until unless a solution is built which allows the employees to keep the same email address for a long period, certificates would have to be re-issued every time an employee changes their email address. 5. Availability and storage of reliable user information 6. Certificate Validity Checking 7. PIN management: smart Card PIN management may cause some problem to the employees..

Define PKI (Public Key Infrastructure) and list and discuss the type.pdf
Define PKI (Public Key Infrastructure) and list and discuss the types of protection that it offers.
Give an example of where PKI is utilized in daily activity,(industry).
Solution
Answer:-
PKI (Public Key Infrastructure) :
Public Key Infrastructure (PKI) is a popular encryption and authentication approach used by
both small businesses and large enterprises.
What Is Public Key Infrastructure (PKI) :
The PKI environment is made up of five components:
1) Certification Authority (CA) -- serves as the root of trust that authenticates the identity of
individuals, computers and other entities in the network.
2) Registration Authority (RA) : -- is certified by a root CA to issue certificates for uses
permitted by the CA. In a Microsoft PKI environment, the RA is normally called a subordinate
CA.
3) Certificate Database : -- saves certificate requests issued and revoked certificates from the RA
or CA.
4) Certificate Store :-- saves issued certificates and pending or rejected certificate requests from
the local computer.
5) Key Archival Server :-- saves encrypted private keys in a certificate database for disaster
recovery purposes in case the Certificate Database is lost.
6) PKI is a very effective method for implementing multi-factor authentication. Some
companies, such as Unisys, require that devices that are attached to the corporate network must
be able to use PKI for the encrypted and authenticated exchange of information.
7) In cryptography, a PKI is an arrangement that binds public keys with respective identities of
entities (like persons and organizations).
8) A public key infrastructure (PKI) is a system for the creation, storage, and distribution of
digital certificates which are used to verify that a particular public key belongs to a certain entity.
Types Protection:
1) Encryption and/or sender authentication of e-mail messages .
2) Encryption and/or authentication of documents .
3) Authentication of users to applications (e.g., smart card logon, client authentication with SSL).
There\'s experimental usage for digitally signed HTTP authentication in the Enigform and
mod_openpgp projects .
4) Bootstrapping secure communication protocols such as Internet key exchange (IKE) and SSL.
In both of these, initial set-up of a secure channel security association uses asymmetric key ,
public key methods, whereas actual communication uses faster symmetric key, secret key
methods.
5) Mobile signatures are electronic signatures that are created using a mobile device and rely on
signature or certification services in a location independent telecommunication environment..

The public key infrastructure (PKI) has been
widely adopted to create, manage, distribute,
store and revoke digital certificates, which plays
an important role in bootstrapping secure com-
munications. A PKI system authenticates entities
with the corresponding public keys and it lays
the security foundation for public-key crypto-
systems in public-key encryption and digital sig-
natures. However, traditional PKI systems suffer
from security breaches, such as single-point-of-
failure and man-in-the-middle attacks due to the
existence of a centralized certificate authority.
In this article, we review the traditional central-
ized PKI system as well as the subjected security
concerns, and then we propose possible solu-
tions to address these issues with the emerging
blockchain technology. Two frameworks are pre-
sented where blockchain is utilized as a public
bulletin board or trusted majority. We implement
the functions to evaluate the off-chain time costs
and on-chain gas costs of the proposal, which
demonstrate the feasibility and practicality of the
proposal.
IntroductIon
Secure key generation and key distribution are
the fundamentals of a cryptographic system.
For example, communications over the Internet
are built on the top of the secure distribution of
public keys and the confidentiality of the corre-
sponding private keys. A common approach to
securely generating and claiming key pairs is to
employ a public key infrastructure (PKI). A PKI
system is a collection of hardware, software,
people, policies and procedures that achieves
the generation, management, storage, distri-
bution, and revocation of keys and certificates
based on public-key cryptography. PKI systems
can be applied to ascertain the identities of differ-
ent authorities and authenticate an entity to the
corresponding public key. It provides underlying
security services for e-commerce, e-government,
office automation, and so on, so that users who
are unknown to one another or physically apart
can communicate securely through the chain of
trust. A PKI system provides fundamental secu-
rity guarantees to many applications. However,
the typical traditional PKI system relies on a cen-
tral authority (CA) to create, store and revocate
digital certificates. In this case, it might trigger
a number of security issues. First, CA can easily
be the target of many attacks. For example, CA
might suffer from network attacks, such as ARP
spoofing, IP spoofing and DNS spoofing attacks,
and moreover single-point-of-failure is another
severe problem. Second, a malicious CA might
cause unexpected disasters to the system since
fraudulent certificate attacks happen frequently.

problems issued by intermediate CAs (https://

Information Leakage Prevention In Cloud Computing
The cloud computing is still in it infancy.this is an emerging technology which will bring about innovations in
terms of businessmodels and applications.the widespread penetration of smartphones will be a major factor in
driving the adoption of cloude computing.however, cloud computing faces challenges related to privacy and
security. Due to varied degree of security features and management schemes within the cloud entities security in
the cloud is challenging. Security issues ranging from system misconfiguration, lack of proper updates, or
unwise user behaviour from remote data storage that can expose user ̳s private data and information to unwanted
access can plague a Cloud Computing. The intent of this paper is to investigate the security related issues and
challenges in Cloud computing environment . We also proposed a security scheme for protecting services
keeping in view the issues and challenges faced by cloud computing.
Cloud computing security issues and challenges
In the last few years, cloud computing has grown from being a promising business concept to one of the fastest growing segments of the IT industry. Now, recession-hit companies are increasingly realizing that simply by tapping into the cloud they can gain fast access to best-of-breed business applications or drastically boost their infrastructure resources, all at negligible cost. But as more and more information on individuals and companies is placed in the cloud, concerns are beginning to grow about just how safe an environment it is. This paper discusses security issues, requirements and challenges that cloud service providers (CSP) face during cloud engineering. Recommended security standards and management models to address these are suggested for technical and business community.

DEVELOPMENT OF SECURE CLOUD TRANSMISSION PROTOCOL (SCTP) ENGINEERING PHASES :...
Cloud computing technology provides various internet-based services. Many cloud computing vendors are offering cloud services through their own service mechanism. These mechanisms consist of various service parameters such as authentication, security, performance, availability, etc. Customer can access these cloud services through web browsers using http protocols. Each protocol has its own way of achieving the request-response services, authentication, confidentiality and etc. Cloud computing is an internet-based technology, which provides Infrastructure, Storage, Platform services on demand through a browser using HTTP protocols. These protocol features can be enhanced using cloud specific protocol, which provides strong authentication, confidentiality, security, integrity, availability and accessibility. We are proposing and presenting the secure cloud transmission protocol (SCTP) engineering phases which sits on top of existing http protocols to provide strong authentication security and confidentiality using multi-models. SCTP has multi-level and multi-dimensional approach to achieve strong authentication and multi-level security technique to achieve secure channel. This protocol can add on to existing http protocols. It can be used in any cloud services. This paper presents proposed Protocol engineering phases such as Service Specification, Synthesis, Analysis, Modelling, and Implementation model with test suites. This paper is represents complete integration of our earlier proposed and published multilevel techniques

Solution
A decade ago, a group of experts estimated the half-life of an engineer\'s technical skills--how
long it would take for half of everything an engineer knew about his or her field to become
obsolete. For mechanical engineers it was 7.5 years. For electrical engineers it was 5. And for
software engineers, it was a mere 2.5 years, less time than it takes to get an undergraduate
degree. Today, those numbers are surely even smaller.
Technology is rushing headlong into the future at a pace that takes one\'s breath away. Personal
computers, the Internet, genetic engineering, advanced materials, new forms of chemical
synthesis--all these things and more are changing our world swiftly, profoundly, and, in most
cases, for the better. But the excitement and the progress come at a cost. Rapid change is not
always comfortable, and no one knows this better than the people whose job it is to stoke the
technological juggernaut.
Think about it. In some specialties, engineers must update half of everything they know every
couple of years, all the while working full-time to design products according to the best
standards of the moment--which might change next month. In even the slower-paced fields,
engineers must reinvent themselves at least once a decade.
There\'s more. A generation ago, an engineer could expect to carve out a niche in one well-
defined area-- automotive steering systems, say, or chemical plant instrumentation--and remain
there for a lifetime. No longer. As technological change accelerates and product lines rise and
fall in ever-diminishing life cycles, engineers find themselves switching jobs more often, to the
point that those starting out today may hold half a dozen jobs over their careers, even if they
manage to remain with the same company throughout. So besides staying abreast of
developments in their own specialties, engineers must be prepared to switch nimbly to a new
field when the old one peters out.
And, to complicate things further, these professional demands come at a time of upheaval in the
employment landscape. Global competition has sparked a wave of downsizings in technology
firms, destroying much of the job security that engineers used to take for granted and pushing
companies to contract out more and more of their design work. Today, service firms such as
Andersen Consulting are the largest recruiters of engineering graduates on some college
campuses, eclipsing the big manufacturing companies in the number of hires.
The bottom line: A large and growing percentage of engineers now work as contract technical
experts, hiring out for a particular job at a particular company, then moving on when it is
finished. They may be independent consultants or they may work for consulting firms, but either
way they don\'t have the long-term stability that joining a traditional manufacturing firm used to
provide.

why is lifelong learning important for Engineers? Give an example to support your argument.
please help me with this ..
Solution
A decade ago, a group of experts estimated the half-life of an engineer\'s technical skills--how
long it would take for half of everything an engineer knew about his or her field to become
obsolete. For mechanical engineers it was 7.5 years. For electrical engineers it was 5. And for
software engineers, it was a mere 2.5 years, less time than it takes to get an undergraduate
degree. Today, those numbers are surely even smaller.
Technology is rushing headlong into the future at a pace that takes one\'s breath away. Personal
computers, the Internet, genetic engineering, advanced materials, new forms of chemical
synthesis--all these things and more are changing our world swiftly, profoundly, and, in most
cases, for the better. But the excitement and the progress come at a cost. Rapid change is not
always comfortable, and no one knows this better than the people whose job it is to stoke the
technological juggernaut.
Think about it. In some specialties, engineers must update half of everything they know every
couple of years, all the while working full-time to design products according to the best
standards of the moment--which might change next month. In even the slower-paced fields,
engineers must reinvent themselves at least once a decade.
There\'s more. A generation ago, an engineer could expect to carve out a niche in one well-
defined area-- automotive steering systems, say, or chemical plant instrumentation--and remain
there for a lifetime. No longer. As technological change accelerates and product lines rise and
fall in ever-diminishing life cycles, engineers find themselves switching jobs more often, to the
point that those starting out today may hold half a dozen jobs over their careers, even if they
manage to remain with the same company throughout. So besides staying abreast of
developments in their own specialties, engineers must be prepared to switch nimbly to a new
field when the old one peters out.
And, to complicate things further, these professional demands come at a time of upheaval in the
employment landscape. Global competition has sparked a wave of downsizings in technology
firms, destroying much of the job security that engineers used to take for granted and pushing
companies to contract out more and more of their design work. Today, service firms such as
Andersen Consulting are the largest recruiters of engineering graduates on some college
campuses, eclipsing the big manufacturing companies in the number of hires.
The bottom line: A large and growing percentage of engineers now work as contract technical
experts, hiring out for a particular job at a particular company, then moving on when it is
finished. They may be independent consultants or they may work for consulting firms, but either
way they don\'t have the long-term stability that joining a traditional manufacturing firm used to
provide.

Which of the following is true of aldol reactions1.The thermodyna.pdf
Which of the following is true of aldol reactions?
1.The thermodynamics and kinetics of aldol reactions can be controlled by base selection.
2.Aldol reactions can be completed by reacting an aldehyde and a ketone in the presence of a
base.
3.The yields of aldol reactions involving only one type of a hydrogen are generally higher than
the yields of those involving multiple types of a hydrogens.
4.Aldol reactions are used to create carbon–carbon bonds.
5.All of the above are true of aldol reactions.
Solution
Answer:
5.All of the above are true of aldol reactions.
Explanation:
Aldol reaction is the reaction between two cabonyl compounds with one carbonyl compound
contains one alpha -hydrogen in the presence of base to give beta hydroxy carbonyl compound.
So option 1 is correct.
The kinetic prodduct is the formation of C-C bond on the less substituted alpha carbon atom, can
be acheived by the bulky base LDA and thermodynamic product is the formation of C-C bond on
the more substituted alpha carbon to the carbonyl carbon can be achieved by the less bulky base
like NaOC2H5. so option 2 is correct.
If there are more kinds of active hydrogens gives mixed aldol product that gives less yield and
the compound with one kind of active hydrogen gives only one product with more yield. So
option 4 is correct.
In aldol reaction there is a formation of c-c bond. so option 4 is also correct..

Solution
1) Programming paradigm is a way or style of writing programming languages.
For example in python, blocks are represented using blocks. In python intendation is important.
IN java, flower/open braces are used.
2)
Procedural programming
This is style of routines and subroutines.
Declaring the subroutine, top of program declaring prototype declaring and bottom of program
writing the implementation of methods.
Also subroutine is accssible is depends on public accessifiers.
3)
OOPS programming language where all variables and methods are accessed via object.
Object is real entity which stores the data.
Java, python,c++ are examples of OOPS programming languages.
4)
Abstract data type is representing the hidden object. It hides the implementation.

Transforming Cultures from Consumerism to Sustainability - Essay.pdf
Transforming Cultures from Consumerism to Sustainability - Essay
Solution
Some 60 percent of ecosystem services are being despoiled or used unsustainably. The damage is
the consequence of cultural systems which give confidence to people to describe their happiness
in addition to success in terms of how much they consume. This propensity, together with
unsustainable population growth rates, is overpowering our finite planet, intimidating to cause
noteworthy disruptions to Earth\'s climate and ecosystems, and consequently to human
civilization. Consumerism has engulfed human cultures and Earth’s ecosystems and if left
unaddressed, we threat global disaster. However if we direct this wave, deliberately changing our
cultures to center on sustainability, we will not only put off disaster, however may steer in an era
of sustainability—one which allows all people to prosper whilst protecting, even restoring, Earth.
World watch Institute\'s Transforming Cultures plan turns a critical eye to how we can transfer
today\'s consumer cultures in the direction of cultures of sustainability. The solution to this
revolution will lie in harnessing institutions which play a vital role in shaping society— like
media, educational services, business, governments, traditions, as well as social movements—to
inspire this new cultural course.
The plan also seeks to bring women into educational, economic, political as well as health parity
with men. This will necessitate the wearing away of cultural norms which endorse early and
frequent childbearing while intensifying women\'s capability to decide when to bear children.
Studies explain that such advances slow and ultimately end population growth, allowing for
more sustainable growth all-inclusive..

Trane has 145 marbles. He gives 20 to Katie, 52 to Gwen, and 31 to Yusef. He keeps the rest.
Who has the most marbles? Trane Katie Gwen Yusef
Solution
Trane has 145 marbles , he gave 20 to Katie and 52 to Gwen , and 31 to Yusef.
It means now
Katie has = 20 ,
Gwen has = 52
Yusef has = 31
and Trane has =145 -20 -52 -31 = 42
It means Gwen has the most marbles , that is 52.

Section 404 of the Sarbanes Oxley Act requires auditors of a public .pdf
Section 404 of the Sarbanes Oxley Act requires auditors of a public company to analyze and
report on the effectiveness of the client\'s internal controls over financial reporting. Describe the
responsibilities that auditors of public companies have to discover and report (a) significant
deficiencies in internal controls and (b) material weaknesses in internal controls. Include a
definition of each item in your answer. Under what condition or conditions can auditors issue an
unqualified or clean opinion on the effectiveness of a client\'s internal controls over financial
reporting?
Solution
Note: Please note, that there is no specific definition of \"Internal Control Deficiency\" and
\"Significant Control deficiency\" in the audit subject. Definition of Material Weakness has been
added. In case of any further clarification please let me know.
Definiton of Internal Control: \"Internal Control\" means the planning of an organisation and all
the policies and procedures adopted by an organisation\'s management to ensure orderly and
efficient conduct of business.
Defintion of Material Weakness: \"Material Weakness\" is a weakness or deficiency in internal
control due to which there is a possibility that the material misstatement in financial statement
will not be prevented or detected on a timely basis.
It is not the responsibility of the auditorto identify each and every deficieny in Internal Control
and express an opinion on it. His responsibility is \"To communicate any significant deficiency
in internal control identified during audit to management/Those Charged With
Governance(TCWG)/Audit Committee.
Auditor can issue an unqualified or clean opinion on the effectiveness of a client\'s internal
controls if their internal controls are seems effective to the auditor, if significant related party
transactions are scrutinized by the management/TCWG, if Management fraud prevented by
Internal Control, if non compliance of Laws & Regulations are prevented and properly followed
by management, if Internal Control designed and implemented in a way so that it can prevent or
detect and correct misstatements in Financial Statement on timely basis..
Reiji and Tuneko Okazaki conducted a now classic experiment in 1968 .pdf
Reiji and Tuneko Okazaki conducted a now classic experiment in 1968 in which they discovered
a population of short fragments synthesized during DNA replication. They introduced a short
pulse of 3H -thymidine into a culture of E. coli and extracted DNA from the cells at various
intervals. In analyzing the DNA after centrifugation in denaturing gradients, they noticed that as
the interval between the time of 3H -thymidine introduction and the time of centrifugation
increased, the proportion of short strands decreased and more labeled DNA was found in larger
strands. What would account for this observation?
a. the ligation of Okazaki fragments by DNA ligase
b. the degradation of Okazaki fragments by DNA polymerase I
c. the accumulation of Okazaki fragments produced on the lagging strand
d. the mutation affecting the activity of DNA ligase
Solution
Answer C: The accumulation of Okazaki fragments produced on the lagging strand
Replication of DNA on lagging strand is discontinuous and replications occur in small sections.
These new stretches of DNA are called Okazaki fragments and each one requires its own RNA
primer. During DNA replication, each Okazaki fragment is separated by their own RNA primers
and are unligated until RNA primers are removed, followed by enzyme ligase connecting
(ligating) an Okazaki fragment onto the (now continuous) newly synthesized complementary
strand. After the introduction of 3H -thymidine (radioactive thymidine) into a culture of E. coli,
3H –thymidine gradually incorporated into both complimentary strands of leading and lagging
strands of DNA during replication. With time, each Okazaki fragment ligated with adjacent
fragment with the help of DNA ligase result in the increase of the length of the complementary
strand. Due to accumulation and ligation of Okazaki fragments produced on the lagging strand,
the proportion of short strands decreased and more labeled DNA was found in larger strands..

Organizations need to have a pool of managerial talent to take on jo.pdf
Organizations need to have a pool of managerial talent to take on jobs from senior managers and
new management jobs that may be created. One way is to hire from outside, another way is to
\"grow your own manager talent pool\" from within.
Create a 700 to 1050 word recommendation that describes how you will grow the manager talent
pool at your organization.
How will you select candidates for your manager development program? For example: select
from existing staff or hire them in? How would you assess their potential so you know who to
pick? For example: interviews, tests. What might you need to do so that you consider all
potential candidates and do not unfairly discrimminate?
How would you develop these candidates and over what time period? What different
jobs/experiences should they have so that at the end of say 2-3 years they are ready for a
management slot? What formal training might they need?
So after all the training and job experience, how will you assess who is ready to move up to the
position of manager? Again, consider how you would make sure you individuals are chosen
fairly and objectively.
What support should be provided to new managers to ensure their success?
Solution
It is clear that there is need for consideration of the managerial talent which is an entire role and
responsibility of the HR management in the context of ensuring an organization retains its
employees and ensuring effectiveness through competition which is an organization strategy to
effectively compete in the market.
.
Selecting candidates for a managerial development program
The main consideration that in selecting various candidates existing in the organization for the
managerial development programs includes;
The process will involve internal selection in the context that the process is less costly as
compared with external hiring where the process is costly due to lack of experience based on our
organizational operations which will require more resources to integrate employees with our
organizational operations. In this regards, to this angle the main assessment considerations will
be based on;
Past performance of potential candidate for the managerial development program in the context
that the candidate should be among the top performers in the organization operations. This is in
regards that if the current performance of an employee is poor this has great prediction for the
future managerial position.
The potential of the candidate which will be based on considerations such as current performance
by the employee, lateral potential in that an employee is able to move into other positions at the
same level, potential of an employee to supervise and relate with other employees and high
potential based on that the employee can be promoted to the managerial position within 1 year or
making multiple move upwards in the next couple of years.
There will also be consideration of the requisite knowledge and ability through clearly outlining
the knowledge and ski.

Militarism Alliances Imperialism Nationalism Class, the powder keg.pdf
Militarism Alliances Imperialism Nationalism
Class, the powder keg that ignited Europe was the assassination of the Archduke Franz
Ferdinand. Nationalist Serbs- the Black Hand assassinated him. They believed in Pan Slavism.
What is Pan Slavism? Why did Russia enter WWI? Who fought on which sides during WWI?
Solution
Pan-Slavism, a development which solidified in the mid-nineteenth century, is the political
philosophy worried about the headway of respectability and solidarity for the Slavic-talking
people groups. Its fundamental effect happened in the Balkans, where non-Slavic domains had
ruled the South Slavs for a considerable length of time. These were chiefly the Byzantine
Empire, Austria-Hungary (both as discrete entities for the vast majority of the period), the
Ottoman Empire, and Venice.
The Pan-Slavism development soon went up against political hints, and in June 1848, while the
Austrian Empire was debilitated by transformation, the Czech history specialist František
Palacký assembled a Slav congress in Prague. Comprising of agents of every Slav nationality
controlled by the Austrians, the congress was proposed to compose agreeable endeavors among
them to compel the Emperor to change his government into an alliance of equivalent people
groups under a vote based Habsburg run the show.
In spite of the fact that the congress had minimal commonsense impact, the development stayed
dynamic, and by the 1860s it turned out to be especially mainstream in Russia, to which
numerous Pan-Slavs searched for authority and also for insurance from Austro-Hungarian and
Turkish run the show. Russian Pan-Slavists, be that as it may, changed the hypothetical bases of
the development. Embracing the Slavophile thought that western Europe was profoundly and
socially bankrupt and that it was Russia\'s noteworthy mission to revive Europe by increasing
political strength over it, the Pan-Slavists included the idea that Russia\'s central goal couldn\'t be
satisfied without the help of other Slav people groups, who must be freed from their Austrian and
Turkish experts and joined into a Russian-ruled Slav confederation.In spite of the fact that the
Russian government did not authoritatively bolster this view, some essential individuals from its
remote division, including its agents at Constantinople and Belgrade, were fervent Pan-Slavists
and prevailing with regards to drawing both Serbia and Russia into wars against the Ottoman
Empire in 1876– 77. At the point when endeavors were made in the mid twentieth century to call
new Pan-Slav congresses and resuscitate the development, the nationalistic contentions among
the different Slav people groups kept their successful cooperation.
Russia entered WW1 due to following reasons:
Russia was drawn into WW1 by similar stumbles and habits that tormented her neighboring
European nations, radical rivalry, harmful patriotism, military haughtiness, and insufficient trust
in tact and dependence on collusions. While Russia enter.

Introduction to Quality Improvement Essentials
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

In the subject of cryptography, what policy or organizational challe.pdf
- 1. In the subject of cryptography, what policy or organizational challenges might impede or prevent the deployment of a worldwide universal Public-Key Infrastructure? Solution Below challenges may present the deployment of Universal PKI : 1. Token Logistics: There are many advantages of implementing PKI on a hardware token, such as a smart card. These include security, portability and ease of use to add other user specific applications and visual information. However, the logistics of managing security tokens requires a considerable effort and cost to a Public-Key Infrastructure implementation. 2. Network Issues: The implementation of PKI will surely add to the network load. The potential additional traffic that should be considered are: i. Certificate issuance ii. Email Usage iii. Directory Replication. 3. Network Issues - Encryption: Usually the organisations implement anti-virus software and on regular basis perform inspection on servers at the perimeter of their networks. Some organizations has security policies that rejects or quarantines encrypted traffic. To provide user-to-user confidentiality, the messages will traverse networks with their payload hidden from inspection by virus and content checking. Possible solutions include: · Performing virus & content checking at the client machine. · Storing user confidentiality private keys on a secure key server. · Co-encrypting messages to a Gateway which then decrypts and checks the message before it is delivered. 4. Email Address in Certificate:
- 2. Usually employees change their email addresses more frequently than the certificate. Until unless a solution is built which allows the employees to keep the same email address for a long period, certificates would have to be re-issued every time an employee changes their email address. 5. Availability and storage of reliable user information 6. Certificate Validity Checking 7. PIN management: smart Card PIN management may cause some problem to the employees.
