A Secure Cloud Storage System with Data Forwarding using Proxy Re-encryption ...IJTET Journal
Cloud computing provides the facility to access shared resources and common support which contributes services on
demand over the network to perform operations that meet changing business needs. A cloud storage system, consisting of a collection
of storage servers, affords long-term storage services over the internet. Storing the data in a third party cloud system cause serious
concern over data confidentiality, without considering the local infrastructure limitations, the cloud services allow the user to enjoy the
cloud applications. As the different users may be working in the collaborative relationship, the data sharing becomes significant to
achieve productive benefit during the data accessing. The existing security system only focuses on the authentication; it shows that
user’s private data cannot be accessed by the fake users. To address the above cloud storage privacy issue shared authority based
privacy-preserving authentication protocol is used. In the SAPA, the shared access authority is achieved by anonymous access request
and privacy consideration, attribute based access control allows the user to access their own data fields. To provide the data sharing
among the multiple users proxy re-encryption scheme is applied by the cloud server. The privacy-preserving data access authority
sharing is attractive for multi-user collaborative cloud applications.

A comparative study of various diagnostic techniques for CryptosporidiosisIOSR Journals
Diarrhoeal disease is a common complication of infection with HIV. Cryptosporidium has gained importance as an AIDS indicator disease and a cause of intractable diarrhoea in immunosuppressed individuals. This warranted a study of stool specimens of HIV positive patients with (n=60) and without (n=60) diarrhoea along with their HIV negative counterparts (n=200). Microscopic examination for ova and cysts were done using wet mount and Lugol’s iodine preparation. Smears were stained with Kinyoun Cold Acid Fast (KCAF) and Auramine ‘O’ fluorochrome (AOF) staining methods to identify Cryptosporidium oocysts. ELISA using Cryptosporidium microplate assay (alexon Inc) for detection of Cryptosporidium antigen was conducted on all stool specimens. By KCAF staining detection of Cryptosporidium in HIV positive subjects with diarrhoea was 20%, by AOF it was 7.5% and by ELISA the detection rate went up to 30%. All the detailed result were statistically compared taking KCAF staining as gold standard which revealed AOF staining to have sensitivity of 36.67% and specificity of 99.31% while ELISA was found to have sensitivity of 83.88% and specificity of 96.55%. Keeping in mind the present scenario of HIV infection in India and more so in Goa, it is recommended to include detection of Cryptosporidium oocysts in routine parasitological examination of stool specimens and an urgent need to standardize a gold standard for various diagnostic tests presently available

Survey on Restful Web Services Using Open Authorization (Oauth)I01545356IOSR Journals
Abstract: Web services are application based programming interfaces (API) or web APIs that are accessed
through Hypertext Transfer Protocol (HTTP) to execute on a remote system hosting the requested services. A
RESTFUL web service is a budding technology, and a light weight approach that do not restrict the clientserver
communication. The open authorization (OAuth) 2.0 protocol enables the users to grant third-party
application access to their web resources without sharing their login credential data. The Authorization Server
includes authorization information with the Access Token and signs the Access Token. An access token can be
reused until it expires. An authentication filter is used for business services. This paper presents a secure
communication at the message level with minimum overhead and provides a fine grained authenticity using the
Jersey framework.
Keywords: Open authorization (oauth), Restful web services, HTTP protocols and uniform resource
identifier(URI).

Ant colony Optimization: A Solution of Load balancing in Cloud dannyijwest
As the cloud computing is a new style of computing over internet. It has many advantages along with some
crucial issues to be resolved in order to improve reliability of cloud environment. These issues are related
with the load management, fault tolerance and different security issues in cloud environment. In this paper
the main concern is load balancing in cloud computing. The load can be CPU load, memory capacity,
delay or network load. Load balancing is the process of distributing the load among various nodes of a
distributed system to improve both resource utilization and job response time while also avoiding a
situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work.
Load balancing ensures that all the processor in the system or every node in the network does
approximately the equal amount of work at any instant of time. Many methods to resolve this problem has
been came into existence like Particle Swarm Optimization, hash method, genetic algorithms and several
scheduling based algorithms are there. In this paper we are proposing a method based on Ant Colony
optimization to resolve the problem of load balancing in cloud environment.

INTRODUCTION
Cloud computing is being rapidly adopted across the IT
industry, driven by the need to reduce the total cost of
ownership of increasingly more demanding workloads. Within
companies, private clouds are offering a more efficient way to
manage and use private data centers. In the broader
marketplace, public clouds offer the promise of buying
computing capabilities based on a utility model. This utility
model enables IT consumers to purchase compute resources on
demand to fit current business needs and scale expenses
associated with computing resources. Thus, cloud computing
offers IT to be treated as an ongoing variable operating expense
billed by usage rather than requiring capital expenditures that
must be planned years in advance. Advantageously, operating
expenses can be charged against the revenue generated by these
expenses directly. In contrast, capital expenses incurred by the
purchase of a system need to be paid at the time of purchase,
but can only be depreciated to reduce the taxable income over
the lifetime of the system.
THE MAIN ATTRIBUTES OF CLOUD COMPUTING
The main attributes of cloud computing are scalable,
shared, on-demand computing resources delivered over the
network, and pay-per-use pricing. This offers flexibility in
using as few or as many IT resources as needed at any point in
time. Thus, users do not need to predict future resources they
might need, and to commit to capital investment in hardware.
This is especially advantageous for start-ups, and small and
medium businesses which might otherwise not be able to afford
the IT infrastructure they need to support their growing
business. At the same time, redirecting capital investment from
IT infrastructure to the core business is attractive even for large
and financially strong businesses.
From a technical perspective, cloud computing brings the
benefits of virtualization and multi-tenancy to scale-out
systems. Virtualization techniques allow multiple system
images to share the same hardware resources: CPU
virtualization techniques create multiple virtual hardware
systems, while network virtualization .
In this paper we are study-ing about cloud computing, their types, need to use cloud computing. We also study the architecture of the mobile cloud computing. So we included new techniques for backup and restoring data from mobile to cloud. Here we proposed to apply some compres-sion technique while backup and restore data from Smartphone to cloud and cloud to the Smartphone.

Cloud computing security through symmetric cipher modelijcsit
Cloud computing can be defined as an application and services which runs on distributed network using
virtualized and it is accessed through internet protocols and networking. Cloud computing resources and
virtual and limitless and information’s of the physical systems on which software running are abstracted
from the user. Cloud Computing is a style of computing in which dynamically scalable and often virtualized
resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or
control over the technology infrastructure in the "cloud" that supports them. To satisfy the needs of the
users the concept is to incorporate technologies which have the common theme of reliance on the internet
Software and data are stored on the servers whereas cloud computing services are provided through
applications online which can be accessed from web browsers. Lack of security and access control is the
major drawback in the cloud computing as the users deal with sensitive data to public clouds .Multiple
virtual machine in cloud can access insecure information flows as service provider; therefore to implement
the cloud it is necessary to build security. Therefore the main aim of this paper is to provide cloud
computing security through symmetric cipher model. This article proposes symmetric cipher model in
order to implement cloud computing security so that data can accessed and stored securely.

Privacy preserving public auditing for secured cloud storagedbpublications
As the cloud computing technology develops during the last decade, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, aiming at achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintenance of a MapReduce cloud, which helps clients generate data tags before uploading as well as audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud+ is designed motivated by the fact that customers always want to encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Improving the Latency Value by Virtualizing Distributed Data
Center and Automation in Cloud.
C.Eng. (Mrs.).Nusrath Sultana B.Tech, AMIEI.
Assistant professor, Global Institute of Engineering and Technology, Affiliated to JNTU-H, India
Abstract :Organization today are leveraging the benefits of cloud computing to increase flexibility, agility and
reduce cost however that flexibility can also pose networking challenges by moving application offsite,
companies need good network connectivity between a data center site and a cloud provider so that user don’t
experience performance degradation. Good connectivity comes in two forms necessary bandwidth and low
latency. Distributed datacenter improves services access latency and bandwidth. Virtualized cloud data center
enables IT organization to share compute resources across multiple applications and user group in a much
more dynamic way than is possible in traditional environment where application, middleware and
infrastructure are tightly coupled and resource allocation are highly static. The goal is to enable users to
reduce the cost and complexity of application provisioning and operations in virtualized data centers. Cloud
environments at the same by automation liberate the operational management from the burden of manual
process.
I. Introduction
Decades of software and hardware purchases made across the enterprise have left systems residing on
grossly underused infrastructure. In fact, companies on average use only 15% to 20% of available server and
storage capacity. Supporting this highly complex, fragmented, and inefficient environment can cost up to nine-
tenths of your annual IT budget. Updates and fixes get done manually, leading to errors, security problems, and
infrastructure downtime. Even worse, time to market and customer satisfaction can suffer. In this paper we will
see how best we can reduce the latency and improve the bandwidth by virtualizing the distributed data center
and automatic configuration.
II. Centralized data center Vs Distributed data center
The debate over centralized versus distributed data center , is seem to the pendulum swinging back and
forth, some companies still consider to keep centralized data centers. This paper presents distributed data center
over centralized data center. Distributed data center will have much lower latency characteristics per application
and per services than those that are deployed centrally. Service provider will gain financial benefit by
distributing their data centers, positioning select services close to the customers who will use them. There are a
number of different storage model in use today such as (1) Storage over IP (SoIP). (2) Fiber Channel over
Ethernet (FCoE). (3) Traditional Fiber Channel. All require a network that offers low latency and high
availability. Deploying distributed datacenter benefit is Wide Area Bandwidth Saving. When application data is
duplicated at multi data centers, clients go to the available data center in the event of catastrophic failure at one
site. Data center can also be used concurrently to improve performance and scalability. Once the content is
distributed to multiple data centers. We need to manage the request for the distributed content, manage the load
by routing user request for content to the appropriate data center, selecting the appropriate data center (which is
based on server availability, content availability), network distance from client to the PC’s and other
parameters.[8]
2.1 Benefits of Distributed Data centers:
1. Archiving data for protection against data loss and corruption, or to meet regulatory requirements
2. Performing remote replication of data for distribution of content, application testing, disaster protection,
and data centre migration
3. Providing non-intrusive replication technologies that do not impact production systems and still meet
shrinking backup window requirements
4. Protecting critical e-business applications that require a robust disaster recovery infrastructure. Providing
real-time disaster recovery solutions, such as synchronous mirroring, allow companies to safeguard their
data operations by:

2.2 The relationship between bandwidth consumed per subscriber to the cost of delivering it:
The cost per application increases linearly for services hosted in centralized data center while it
remains relatively stable for applications hosted in a distributed data center.
Cost per application, varying number of subscribers/application
Figure: 1
2.3 The relationship between the cost of delivering an application and the growth rate in the number of
subscribers using it:
Here the cost advantage of the distributed data center is significant as the application becomes more
popular. Network is a critical resource in the cloud to automate and more effectively manage and distribute
resources for better performance.
Figure: 2
III. Virtualized cloud datacenters
Virtualization: A transparent abstraction of computer resources making a physical resource appears as multiple
logical ones. Virtualization increases utilization of server, reduce data center footprints, and minimize power
requirement[6].For example VmWare offers virtual private networking capabilities as part of its VShield Suite
of products. Vshield protects application in the virtual data center against network based threats[2]
3.1 Benefits of Virtualization:
1. Enhance service level: provision services and resources to the business more quickly; often they are able
to reduce the cycle time from service request to service availability from multiple weeks to just a few days
or hours in the case of self service solution.
2. Cost Saving: Consumption based metering and capacity planning helps IT spending with business needs
and ensures optimal use of available system application and staff resource. Virtualization greatly reduces
capex and opex, the ratio of administrators to physical and virtual server from 1:30 to 1:1000+ results in
significant to IT product and cost saving.
3. Improve operational efficiency: Significant expansion of automation and orchestration strategies across
the internal data center environment improves IT operational efficiency.
4. Increase availability and reduce energy consumption: power consumption will always be less after
virtualizing as a result of computing consolidation and physical reduction of the amount of IT equipment.
Which is a contribution to green computing?
5. Improve overall business flexibility and agility: By providing better optimize end-to-end application
performance and availability by reducing downtime, maintaining more consisting patching and security
processes and improving the ability to diagnose and reduce the root cause of problem overall business
flexibility will improve.
IV. Network of cloud to improve latency:
Here we are architechuring the multi cloud support and are so found on zero modification of server and
applications where we have a freedom to use a cloud that is ‘closer” without changing the configuration where
we can achieve our task with low latency, high SLA and better pricing. By virtualizing the distributed data
center we can build on demand virtual data center in multitenant environment which rapidly provision

application to meet business needs. Now we need a network in the network pool. (Network pool is a collection
of virtual machine) network where traffic at each network is isolated at layer 2 when it is available to be
consumed by organization to create organization network and Vapp network. Here we are making data centre
behave like a cloud(share pool of services), at layer 2 instead of having a physical partition we go by logical
partition which enables secure sharing of data between data centers and extend it to WAN to connect with other
cloud.
Jupiner simplifies the data center network and eliminates layer of cost and complexity with a 3-2-1
data center network architecture using technologies such as virtual private LAN services(VPLS).Network
Virtualization on juniper network MX Series 3D universal edge router, Virtual chassis on juniper network EX
series Ethernet switches, and Juniper network QFabric architecture on QF X series product family. See for
example The Cloud Ready Data Center Network of Jupiner Network[3].
By using VPLS, MPLS, VPRN, PBB we can address the challenges of multi tenancy, mobility,
scalability, High availability, low latency [1].
4.1Components of a virtual network:
1. Network hardware such as switches and network adapter also know as network interface cards (NIC).
2. Network element such as firewalls and load balancers
3. Network such as virtual LAN (VLAN) and containers such as VM and Solaris container.
4. Network storage devices.
5. Network M2M (machine to machine) elements such as telecommunication 4G HLR and SLR devices.
6. Network mobile element such as laptops, tablets and cell phone.
7. Network media such as Ethernet and fiber channel.
4.2The importance of network bandwidth for storage:
Cloud Computing offers IT far greater flexibility in how it delivers services but that flexibility can pose
networking and storage challenges [5].Storage networks with plenty of bandwidth are also a valuable asset in
virtual infrastructures. The required amount of storage bandwidth depends not only on the number of
transactions but also on the transaction size. Windows File Servers, for example, tend to use tiny transactions to
access the storage, and database servers use medium-size transactions.
In both cases, these workloads will likely be limited by the storage's transaction rate, long before
network bandwidth becomes a factor. For low-utilization, easy-to-virtualized VMs, the storage network won't
be limiting, even at GbE speeds. For the more critical, resource-intensive VMs, however, you'd better make sure
you have dozens of spindles or a fair amount of solid-state drives before you start demanding faster storage
networks
.
4.3 Backups for network bandwidth:
As we've moved from a 9-to-5 working day to the always-on Internet age, the working day overlaps
with the backup window -- which is when organizations back up their servers, usually during off peak times.
Now companies need full-speed performance during a backup, so the network better not be saturated.[6]
Backups involve large transactions and can quickly fill a network. As such, it's common sense to have
a nice, big pipe to carry the data. If that's the case, the storage disks will be the limiting factor, rather than the
link itself. More specifically, if backup tool uses agents inside the VMs, then we require big pipes into the
virtual hosts to avoid a blowout during the backup windows. (Also make sure your hosts have ample CPU and
RAM to cope with this load spike.). Therefore, connecting the backup server to the storage array, using the
biggest pipe available, is definitely a good idea. If we have a fast network between backup server and main
storage, it make sense to have a slower network for hosts? If new equipments are buyed, then probably not. The
incremental cost of fast network ports won't be much, and over time, the demand for bandwidth will likely
increase. To solve the problem of backup speed, we probably buy faster ports for server and storage.
IT pros often cite virtualization and backups as reasons why they need more network bandwidth, but
we don't necessarily need a 10 GbE network to maintain a high level of performance .On the surface, it makes
sense that a virtual infrastructure needs plenty of network bandwidth. Let's say that an organization just
consolidated 20 physical servers, each with two Gigabit Ethernet (GbE) ports, into one virtual host. Surely that
means the host needs more than a few GbE ports?
More on network bandwidth in virtual data centers 10 GbE: Cutting cabling, boosting virtualization
network management, Virtual networking design, configuration and management guide.More on network
bandwidth in virtual data centers 10 GbE: Cutting cabling, boosting virtualization network management, Virtual
networking design, configuration and management guide.The reality is that almost all of those physical hosts
didn't use their full network bandwidth, apart from tiny bursts. So sharing a GbE port among a dozen virtual
machines (VMs) won't be a problem. Virtualization tends to increase the average utilization of these ports from
less than 1% to 5% or 10%. The VMs just don't need a lot of network bandwidth.
4. Improving The Latency Value By Virtualizing Distributed Data Center And Automation In Cloud.
www.iosrjournals.org 27 | Page
That said the virtualization hosts require fast ports, mostly for transferring VMs between hosts. Moving
16 GB worth of a VM’s contents during a powered-on live migration will saturate a GbE port for a few minutes.
The issue is exacerbated when migrations involve a huge amount of RAM.If virtual host with 128 GB of RAM
is filled to capacity, it may take a half an hour or more to migrate all of the VMs using a single GbE port. If we
migrating these VMs because of an impending physical failure, it will feel a lot longer. (Just imagine that
feeling when a host with terabytes of memory is about to fail.) But emptying the same 128 GB host
with 10GbE connection will take about five minutes, reducing the risk of a VM outage because of a virtual host
failure.
V. Automation and orchestration of cloud
Automation and orchestration are often lumped under the same heading and no wonder their roles are
often confused. For some the two words are synonymous: for other the phase”automation and orchestration” is
treated as a single word. [4]. Automation is generally associated with a single task where as orchestration is
associated with a workflow process for several tasks. Save time and money on infrastructure management
processes such as asset tracking, application and patch provisioning, code deployment and rollback, monitoring
and failover, and assigning computing resources. The virtualization can reduce the provisioning time but not
installation time. The IT staff uses labor – intensive management tools and manual script to control and manage
a data center infrastructure. But they won’t be able to keep pace with continuous stream of on figuration
changes associated with clouds dynamic provision and virtual movement nor can they maintain access and
security changes. That is why process automation becomes so important in a cloud. A shift to standardized
service centric delivery model, pared with extensive use of automation and orchestration technologies, can
significantly improve IT operation productivity and end-to-end service levels [7].
Automation and orchestration helps to make infrastructure changes more rapidly, but these changes
have to be recorded nearly simultaneously so that orchestration function has up-to-date configuration data
needed to make decision, such as CPU allocation and storage. The rapidity of change stemming from
automation and self-service in cloud environments requires a more efficient approach to configuration
management and change management inside the IT organization Configuration Management Database (CMDB)
can record these changes in real time.
Figure: 3
VI. Conclusions And Future Work
In cloud computing now a days the more concerned area is latency value .In this paper we try to solve
the latency value by making use of virtualized distributed data centres and at the same time by automating the
configuration which will avoid the manual error and complexity to manage servers and virtual network by
server manager and network manager. Effective automation virtual system attributes to support for
heterogeneous physical and virtual environment; simplify, integrate and standardize workflow; ability to
integrate infrastructure, operating system, and application software; self-serve provisioning interface. Without
automation and orchestration tools, it has to manually reprovision and optimize resources to reflect even the
smallest changes in an environment. The future work emphasis on enabling effective energy management
through automation and real time monitoring.
