This document discusses implementing trust negotiations in multisession transactions. It proposes a framework that supports voluntary and unexpected interruptions, allowing negotiating parties to complete negotiations despite temporary unavailability of resources. The Trust-x protocol addresses issues related to validity, temporary loss of data, and extended unavailability of one negotiator. It allows a peer to suspend an ongoing negotiation and resume it with another authenticated peer. Negotiation portions and intermediate states can be safely and privately passed among peers to guarantee stability for continued suspended negotiations. An ontology is also proposed to provide formal specification of concepts and relationships, which is essential in complex web service environments for sharing credential information needed to establish trust.
BLOCKCHAIN-BASED SMART CONTRACTS : A SYSTEMATIC MAPPING STUDY csandit
An appealing feature of blockchain technology is smart contracts. A smart contract is
executable code that runs on top of the blockchain to facilitate, execute and enforce an
agreement between untrusted parties without the involvement of a trusted third party. In this
paper, we conduct a systematic mapping study to collect all research that is relevant to smart
contracts from a technical perspective. The aim of doing so is to identify current research topics
and open challenges for future studies in smart contract research. We extract 24 papers from
different scientific databases. The results show that about two thirds of the papers focus on
identifying and tackling smart contract issues. Four key issues are identified, namely, codifying,
security, privacy and performance issues. The rest of the papers focuses on smart contract
applications or other smart contract related topics. Research gaps that need to be addressed in
future studies are provided.
Nowadays everyone uses their personal identification documents on a regular basis, which gets shared with third parties without their explicit consent and stored at an unknown location. Companies such as government institutions, banks, credit agencies and other financial organizations are considered to be the weakest point in the current identity management system as they are unfortified to theft and hacking of data. Although the financial services sector have been seeking solutions for identity problem for a long time, it is only now that a viable solution has arrived in form of blockchain. KYC Know Your Customer using Blockchain eliminates the repeated KYC checks that banks currently perform by maintaining a common secure database in a blockchain. The nature of a blockchain ensures that unauthorized changes to the data are automatically invalidated. The proof of reputation concept makes the verification process more robust and secure. Decentralized computing architecture, blockchain will allow for the accumulation of data from multiple authoritative service provider into a single immutable, cryptographically secured and validated database. Blockchain KYC solution take advantages of a secure, public digital ledger to give almost instantaneous and truly secure verification of identity. Due to the immutable and unalterable nature of the record kept in the blockchain, fraud could become a thing of the past.

A blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating parties. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased. The blockchain contains a certain and verifiable record of every single transaction ever made. Bitcoin, the decentralized peer to peer digital currency, is the most popular example that uses blockchain technology. The digital currency bitcoin itself is highly controversial but the underlying blockchain technology has worked flawlessly and found a wide range of applications in both the financial and nonfinancial world. The main hypothesis is that the blockchain establishes a system of creating a distributed consensus in the digital online world. This allows participating entities to know for certain that a digital event happened by creating an irrefutable record in a public ledger. It opens the door for developing a democratic open and scalable digital economy from a centralized one. There are tremendous opportunities in this disruptive technology and revolution in this space has just begun. This white paper describes blockchain technology and some compelling specific applications in both the financial and nonfinancial sector.

Electrically small antennas: The art of miniaturizationEditor IJARCET
We are living in the technological era, were we preferred to have the portable devices rather than unmovable devices. We are isolating our self rom the wires and we are becoming the habitual of wireless world what makes the device portable? I guess physical dimensions (mechanical) of that particular device, but along with this the electrical dimension is of the device is also of great importance. Reducing the physical dimension of the antenna would result in the small antenna but not electrically small antenna. We have different definition for the electrically small antenna but the one which is most appropriate is, where k is the wave number and is equal to and a is the radius of the imaginary sphere circumscribing the maximum dimension of the antenna. As the present day electronic devices progress to diminish in size, technocrats have become increasingly concentrated on electrically small antenna (ESA) designs to reduce the size of the antenna in the overall electronics system. Researchers in many fields, including RF and Microwave, biomedical technology and national intelligence, can benefit from electrically small antennas as long as the performance of the designed ESA meets the system requirement.
Trust in E- and M-Business - Advances Through IT-SecurityOliver Pfaff
SACIS Conference 2002. Istanbul, Turkey
E- and M-Business are mega-trends that create new business opportunities and provide potentials to optimize existing processes. These prominent notions stand for the digital representation of business processes.
Organizations that implement such electronic business processes want to enable ubiquitous access to their services for suppliers, partners, and customers. To achieve this goal, public network infrastructure, e.g. the Internet and wireless networks, are integrated.
Business is based on the principle of trust. Trust services such as authentication, authorization, non-repudiation, and privacy are well established in traditional business. The implementation of digitalized business processes over public network infrastructure requires to adequately transform such trust services into the digital world.
This presentation examines IT-security technologies to achieve digital trust services that are required for E-/M-Business.
Smart contracts are the next version of automated contracts where the user won't have to rely on trust. Smart contracts are automated algorithmic digital forms of contracts where parties can exchange assets without any intermediaries based on specified rules. Here, the program within the smart contract will self-execute based on the conditions previously defined by the parties.
There are certain benefits to using smart contracts such as autonomous, secured, interruption-free, trustless, cost-effective, fast performance, and accurate and error-free. But here, we will analyze the examples of smart contracts, such as how it can be useful in digital identity, supply chain management, insurance, etc.
To help you understand how smart contracts work or how you can utilize this new form of technology for your personal gain, or company 101 Blockchains offers an array of courses. You can use these courses to learn more about smart contracts and its role in various sectors.

The rise of blockchain promises to bring disruption to commercial insurance by fundamentally reshaping principles and processes that have governed the industry since the 17th century. Blockchain offers a more efficient alternative to the processes the insurance industry developed as an answer to the absence of mutual trust between affected parties and a lack of end-to-end transaction transparency.
In this report we address how blockchain can create trust and drive operational excellence, and we assess its wider implications for commercial insurance brokers.

Blockchain technology could help brokers maximize their operational efficiencies by using smart contracts to automate key processes, freeing them to focus on value-added services that drive customer loyalty.
Cross domain identity trust management for grid computingijsptm
The grid computing coordinates resource sharing between different administrative domains in large scale,
dynamic, and heterogeneous environment. Efficient and secure certificateless public key cryptography (CLPKC)
based authentication protocol for multi-domain grid environment is widely acknowledged as a
challenging issue. Trust relationships management across domains is the main objective of authentication
protocols in real grid computing environments. In this paper, we discuss the grid pairing-free certificateless
two-party authenticated key agreement (GPC-AKA) protocol. Then, we provide a cross domain trust
model for GPC-AKA protocol in grid computing environment. Moreover, we analysis the GPC-AKA
protocol in multiple trust domains simulated environment using GridSim toolkit.

SmartQuora - Learn to build a Smart Contract application on Hyperledger Block...Srini Karlekar
SmartQuora is an application that enables knowledge sharing among participants while incentivizing answers that are meaningful and well-explained. Inquirers pose questions with a reward for the best answers and a due-date by which they are looking for an answer. Responders compete with each other to provide the best answers. Participants can like or dislike answers. When the due-date arrives the answers are tallied and the reward is shared proportionately among the responders such that the best answers gets the most earnings. To avoid abuse of the platform, inquirers cannot answer their own questions and respondents cannot vote for their own answers.
Technically speaking, SmartQuora is a DApp (Decentralized Application) built on top of the HLF - Hyperledger Fabric Blockchain decentralized peer-to-peer network. It uses Smart Contracts built using HLF Composer API to represent Questions and Answers which contains rules to manage the process and payout.
SmartQuora uses a Javascript-based front-end web application to communicate withe the Blockchain platform on which the Smart Contracts reside using a RESTful interface. It uses Passport for authentication of participants using OAuth protocol and allows maintenance of their digital wallets through which the participants can manage their Digital Identities. These Digital Identities are generated and managed using the Hyperledger Fabric platform.

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Abstract— A trust negotiation is a mutual attribute-based
authorization protocol between two entities. Trust
Negotiation is an approach to regulate the exchange of
sensitive information during this process. The proposed
framework is a multisession dependable approach to trust
negotiations. This framework supports voluntary and
unpredicted interruptions, enabling the negotiating
parties to complete the negotiation despite temporary
unavailability of resources. The Trust-x protocol
addresses the issues related to validity, temporary loss of
data, and extended unavailability of one of the two
negotiators. A peer is able to suspend an ongoing
negotiation and resume it with another (authenticated)
peer. Negotiation portions and intermediate states can be
safely and privately passed among peers, to guarantee the
stability needed to continue suspended negotiations.
Detailed analysis has been depicted on Trust-x protocol
which has several key properties, including validity,
correctness, and minimalist. This system also withstands
the most significant attacks. An ontology environment is
also proposed to provide formal specification of concepts
and their interrelationships. This is very essential in
complex web service environments. It possesses the
purpose of sharing information about credentials and
their attributes, needed for establishing trust.
Keywords- Security and management, dependability,

I. INTRODUCTION
Trust negotiation is a mechanism supporting
complex, distributed, rule-based access control for
sensitive information and resources, through the
controlled release of credentials. A trust negotiation is a
mutual attribute-based authorization protocol between
two entities.
The main focus of Trust Negotiation is an
approach to gradually establishing trust between
strangers online through the iterative exchange
of digital credentials. In contrast to a closed system,
where the interacting entities have a preexisting
relationship (often proved by typing a username and
password), and trust negotiation is an open system, and
complete Strangers can build trust in one another. This
is done by disclosing digital credentials.
Digital credentials are the computer analog to
paper credentials, such as a driver's license, credit card,
or student ID. Rather than proving the credential
owner's identity, digital credentials assert that their
owner possesses certain attributes. A student might
receive a credential from his or her university that
certifies that they are a student at that university. The
student could then use that credential, for example, to
prove they are a student in order to qualify for a student
discount at an online bookstore. Credentials are
digitally signed in order to allow third parties to verify
them.
The scope of this project is to build trust
negotiations that offer a general solution for secure
transactions. The core of our approach is a trust
negotiation protocol supported by the Trust-X system.
This protocol, referred to as multisession trust
negotiation, involves the exchange of digital credentials
protected by rule based disclosure policies (referred to
as disclosure policies)which make it possible for two
(or more) peers to establish mutual trust, so to carry on
tasks such as the exchange of sensitive resources or
access to a protected service. And by this it supports
crash recovery and the possibility of completing the
negotiation over multiple sessions in secure manner.
II. RELATED WORK
The existing trust negotiation systems,
however, do not currently support any form of
suspension or interruption, and do not allow the
negotiators to be replaced (or delegated) while the
negotiation is ongoing. Interruptions in ongoing trust
negotiations can be the result of external, unforeseeable
events (e.g., parties’ crashes, faulty transmission
channels), or decisions by the involved parties. A party

may not be able to advance the negotiation for
temporary lack of resources. Or the party may not have
readily available the credentials required by the
counterpart, although eligible to them.
Typically, these approaches rely on strong
cryptographic assumptions, and are seldom applicable
in many real-world scenarios, where properties, stated
in digital credentials, actually need to be disclosed in
clear and not only proved to be true. For example, just
proving the possession of a valid credit card is not
sufficient to complete a transaction, and actual account
information is to be supplied in order to enable
charging the amount spent. Additionally, protocols that
rely on oblivious credentials or anonymous credentials
do not allow parties to follow the progress of the
negotiation, since information regarding policies
satisfaction is hidden for confidentiality purposes. It is
thus crucial to extend trust negotiation protocols along
several dimensions.
Negotiations may last a considerable time span
and the involved parties may not be able to
support long negotiations.
Party may not be able to advance the
negotiation for temporary lack of resources.
Once such a credential is disclosed, it cannot be
reused. Hence, completing a negotiation in
which such type of credential is used becomes
crucial.
Interrupted negotiations however represent not
only undesired events, but also vulnerabilities
that could facilitate malicious attackers’
eavesdropping and other behavior.
III.PROPOSED SOLUTION OF TRUST
NEGOTIATION
Ontologies provide a formal specification of
concepts and their interrelationships and play an
essential role in complex web service environments.
It will help to, the data are retrieved correctly and the
relationships between the objects are found
Ontologies in Trust Negotiation
In trust negotiations Ontologies have the
purpose of sharing information about
credentials and their attributes, needed for
establishing trust.
Concept as tuple C= <Keyword Set, Lang set>
Set of Keywords Set of Attributes
- Each attribute in Lang Set implements concept C
- We make use of a Translation function to compare
values of two semantically equivalent attribute
conditions
We assume that there are a number of finite well-
defined concepts in the ontology.
A same concept can be implemented by alternative
credentials/attributes
E.g:
<{sex,gender}{passport.gender,drivingLicence.sex}>
Keywords Set of alternative attribute names
and/or credentials
Property-based policies
A property based policy lists the properties the
counterpart has to provide and the conditions it
must satisfy in order to obtain some resources
(loan,{MaritalStatus,Country},
{country=USA})
Disclosure policies implement property based
policies by associating credential/attribute names
to concepts
- Loan,Marriage
Certificate(),id_card(country=USA)},
- Example:
R Marriage Certificate (), id (age > 25).
To satisfy this disclosure policy, the subject can
either provide the disclosure set
DSet_1 = {Marriage Certificate, id.age, id.country}
DSet_2 = {Marriage Certificate, id.age}

The subject will provide DSet_2 if it can blind all
other attributes of id. The subject may provide
DSet_1 if the most blinded view containing age
also reveals id.country.
IV.IMPLEMENTATION OF TRUST
NEGOTIATION
Negotiation Tree Switching Process
Negotiation Tree setup
In this module to implement a Negotiation tree
(NT) which is a data structure that keeps track of
negotiation process. Initially the tree is routed between
the nodes formally modeled as T= {N, R, E} where N
denotes the set of nodes, R denotes the root of the tree,
and E the set of Edges .Each node is appended in the
tree according to the policies and the dependencies of
the nodes. The NT is rooted from the requested source
and is initialized when the negotiation starts.
Negotiation Tree Transaction
The transaction of the negotiation tree is based
on two phases-policy evaluation phase and credential
evaluation phase. Negotiation is initiated from the
policy evaluation phase, and once the policy evaluation
phase is completed then the credentials are disclosed
during the credential exchange phase. The transaction
of tree is done by multi edge links (several simple
edges) in which each node consist of policy rules. NT
consist of two states- deliv state and open state where
the deliv state denotes a delivery resource, that is, a
node is ready to deliver credential . And the open state
denotes that node is not yet ready for delivering the
credential. During negotiation, save points are
employed to save the negotiation state, validity checks
concerning events which may happen during the
negotiation suspension. The transaction completion of
policy evaluation phase is signaled by a portion of the
tree rooted at the requested resource by the deliv state
that we refer to as valid view.
Negotiation, Suspension, and Nodes Commitment
Process
In this module, the negotiation suspension and
nodes commitment is done. When particular peer
suspends the transaction it will redirect the transaction
to another node which will resume the negotiation. For
every node in the pruned negotiation tree, peer
computes the corresponding committed nodes. If either
an interruption or a suspension occurs for a few
negotiation rounds, the peers will periodically update
their committed versions of the tree.
Tree Splitting and Sharing with Security
In this module to implement the splitting and
sharing of negotiation tree. When the negotiation is
suspended during the policy evaluation phase or
credential evaluation phase by P2, P2 serializes the
negotiation tree and generates the encrypted version of
credentials. This serialized version(S) of the tree is used
as an input for the secret sharing scheme, where P2
splits S into (S1, S2, S3…. Sn) and distributes these
shares to its trusted nodes and process will be resumed
only by the trusted peer.
Multisession Negotiation
In multisession negotiations it allows
negotiations to be conducted within multiple separate
sessions. Consider negotiations between two peers, say
P1 and P2, if there is an interruption in P2 the
negotiation gets suspended and P2 processes the NT
tree in order to hand it to another peer, to resume the
negotiation, by pruning the delivery nodes from NT and
it is resumed by different peers. For example, P2 can
be replaced by peers, provided that the replaced or
delegated peer (e.g., (P3…Pn)) has the ability to
complete the previously started negotiation.
Tree Recovery Process
When the peer P3 is selected, it builds its
version of negotiation tree from the commit and builds
its credentials.P2 sends the novel negotiation tree to P3
and then P3 resume the negotiation. So by this the
negotiation gets started and encrypted credentials are
sent from P2 to P3 Credi, P2 sends the corresponding
keys to P1 to decrypt the credentials.

Sharing the Trust Sequence
MS Protocol for Credential Exchange
In this module, MS protocol is implemented to
exchange the credentials in a secure manner by
encryption. Consider peer P1 and peer P2 are going to
exchange credentials based on the particular terms.
During the credential evaluation phase P2 has lost
communication with P1.So it redirects the transaction
by distributing the credentials to its trusted peers
(P3,P4,….P N) after encrypting the credentials by a key
k. And P2 sends this key to P1 to decrypt the
credentials. If P3 is the first peer responded to P2, P2
will send the P3 ID to P1 and now P1 and P2
reconstructs the sequence, and exchange the remaining
credentials. Based on the corresponding terms stored in
the C seq, P3 is able to verify the validity of each
credential and whether or not it satisfies the
corresponding term. And P3 at its end sends
sequentially the P2 encrypted credentials to P1, which
can verify them by using the key k s obtained by P2.

Ontologies in Trust Negotiations
Usually TN(Trust Negotiations) requirements
are specified by means of credentials:
- Digitally signed documents containing attributes
that describe properties of the subject.
- Instances of credential types
Credential types provide a syntactic structure
of information but do not specify anything about the
interpretation of the attributes contained in the
credential types.
The lack of semantic in credentials/attributes
makes it impossible to automatically detect
relationships between attributes belonging to different
credentials.
To solve this problem of semantic conflicts,
introduce the use of ontologies
V.CONCLUSION
The proposed solution is found to be very
effective by using ontology. The system carry on tasks
such as the exchange of sensitive resources or access to
a protected service using multisession trust negotiation,
negotiation portions, intermediate states can be safely
and privately be transferred among peers. It also
provides a mechanism for recovering from data losses
which may occur at one of the involved peers. So, we
have carefully considered all possible issues related to
validity, temporary loss of data, and extended
unavailability of one of the two negotiators. To solve
this problem of semantic conflicts with the help of
introducing ontologies in trust negotiations.
