Key-exposure resistance has always been an important issue for in-depth cyber defence in many security applications. Recently, how to deal with the key exposure problem in the settings of cloud storage auditing has been proposed and studied. To address the challenge, existing solutions all require the client to update his secret keys in every time period, which may inevitably bring in new local burdens to the client, especially those with limited computation resources such as mobile phones. In this paper, we focus on how to make the key updates as transparent as possible for the client and propose a new paradigm called cloud storage auditing with verifiable outsourcing of key updates. In this paradigm, key updates can be safely outsourced to some authorized party, and thus the key-update burden on the client will be kept minimal. Specifically, we leverage the third party auditor (TPA) in many existing public auditing designs, let it play the role of authorized party in our case, and make it in charge of both the storage auditing and the secure key updates for key-exposure resistance. In our design, TPA only needs to hold an encrypted version of the client’s secret key, while doing all these burdensome tasks on behalf of the client. The client only needs to download the encrypted secret key from the TPA when uploading new files to cloud. Besides, our design also equips the client with capability to further verify the validity of the encrypted secret keys provided by TPA. All these salient features are carefully designed to make the whole auditing procedure with key exposure resistance as transparent as possible for the client. We formalize the definition and the security model of this paradigm. The security proof and the performance simulation show that our detailed design instantiations are secure and efficient.

The main problem is to avoid the complexity of retrieving the video content without streaming problem in multi network clients. The proposed work is to improve Collaboration among streaming contents on server resources in order to improve the network performance. Implementing network collaboration on a content delivery scenario, with a strong reduction of data transferred via servers. Audio and video files are transmitted in blocks to clients through the peer using the Network Coding Equivalent Content Distribution scheme. The objective of the system is to tolerate out-of-order arrival of blocks in the stream and is resilient to transmission losses of an arbitrary number of intermediate blocks, without affecting the verifiability of remaining blocks in the stream. To formulate the joint rate control and packet scheduling problem as an integer program where the objective is to minimize a cost function of the expected video distortion. Suggestions of cost functions are proposed in order to provide service differentiation and address fairness among users.

Media has been a very important medium for entertainment and communications and the captured media was transmitted in analog form. Media providers do not want their end users to store and duplicate the streamed media because the end user can freely distribute the streamed media without any control from the source. Hence while dealing with media streaming, replay protection and integrity protection are the most important factors. The main aim of this paper is to implement the concept of WebRTC to stream the media between the participating end points which is a powerful tool used to incorporate RTC capabilities into browsers and mobile applications. The aim is to develop a secure media stream from an end point that flows through the Open Network Adapter to the Avaya Media Server (AMS) and is hosted by an application on the Engagement Development Platform. The Open Network Adapter with Avaya Fabric Attach is capable of securing the required flow.

Overview of message oriented middleware technology (MOM). Message Oriented Middleware allows asynchronous operation between sender and receiver of information. This greatly reduces temporal coupling and allows building flexible and extensible application architectures. Message queues managed by message brokers are used as information exchanges between sender and receiver. The subscribe-publish pattern allows producers and consumers to share information through message brokers without any direct coupling between them. Various message oriented protocols like MSMQ, AMQP, XMPP and MQTT have emerged that serve the diverse needs of different environments.

Currently, cloud service providers have used a variety of operational mechanisms to support the company's business processes. Therefore, the services are stored on the company's server, which presents in the form of infrastructure, platform, software, and function. There are several vulnerabilities that have been faced in the implementation such as system failure, natural disasters, human errors, or attacks from unauthorized parties. In addition, the time of unavailability of services can be minimized by doing an LM, in which many servers have been used the containers to behave like a service provider. Actually, its existence replaces the virtual machine that requires more resources although the process only can be done through docker with checkpoint and restore in userspace (CRIU). In this research, LM processes are done to the docker container using CRIU by analyzing the quality of service (QoS), memory, and CPU usage. Thus, the simulation is carried out by establishing the LM using 2 (two) different platforms through scenarios with one and three containers respectively. The performance analysis results aim to examine several indicators in comparison with the achievable result to reduce problems that occurred in the cloud service.

In this paper we have to study the different types of the topologies like Bus Topology, Ring Topology, Star Topology, Mesh Topology and Tree Topology. In this paper we have considered above five topology uses and its merits and demerits that will study will help to know that which structure or topology is best for which organization or business. We have to study the topology and finally we have to find the fact that all topologies are alternate options for business like that Bus Topology is use full for small network but its some demerits so its alternate option is Ring Topology. So finally, we can say that all topologies have some extra and different feature are available from other topology and that features are making it special from other topology.

Abstract Live Streaming and Video on Demand are the trending technologies nowadays over the internet. It provides the mechanism to deliver multimedia content such as audio or video to the large number of audience. However internet based services face the problem of QOS (Quality of Service) due to the instability faced in networks. Performance gets degraded when serving content to large number of consumers. Despite following the modern architectural design, precise estimate of resources such as bandwidth and server load is a challenging task.. In this paper we delve into the architectural and performance issues of running these kinds of services. Our study demonstrates that the streaming architecture and Security issues are the challenges faced by these technologies. Moreover resources such as bandwidth and design of networks degrade the quality of multimedia data delivered to users. Thus in order to have best experience of streaming and Video on demand services, these issues must be addressed. Keywords— Live Streaming, VOD (Video On Demand), P2P Streaming, Client-Server Model.

Abstract Mobile Ad Hoc Network is a infrastructure less network it is one of the most important and highly unusual application, which is famous among critical operations like warfare use, emergency recovery because of its self configuring nature of nodes. MANETs does not require any centralized administration, it dynamically forms a temporary network with the changing topology. Due to its open environment and irregular distribution of nodes MANET is vulnerable to malicious attack hence a new intrusion detection system named EAACK is introduced. This scheme demonstrates the complexity of malicious behavior detection rate in certain situations without greatly affecting the network performance. EAACK is a acknowledgment based intrusion detection system it is required to ensure that all the acknowledgment packets are authentic and unattained hence all the packets are signed digitally before they are sent out and till the receiver accepts, due to the usage of both digital signature and acknowledgment packet it causes a great network overhead. This paper proposes and enforces a hybrid cryptography technique in order to minimize the network overhead caused by digital signature. Keywords: EAACK, Hash algorithm, Wi_max 802.16, Caesar cipher, XOR cipher, XTEA.

Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized data deduplication. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself.We also present several new deduplication constructions supporting authorized duplicate check in a hybrid cloud architecture. Security analysis demonstrates that our scheme is secure in terms of the definitions specified in the proposed security model. As a proof of concept, we implement a prototype of our proposed authorized duplicate check scheme and conduct testbed experiments using our prototype. We show that our proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.

Implementation is the stage of the project when the theoretical design is turned out into a working system. Thus it can be considered to be the most critical stage in achieving a successful new system and in giving the user, confidence that the new system will work and be effective. The implementation stage involves careful planning, investigation of the existing system and it’s constraints on implementation, designing of methods to achieve changeover and evaluation of changeover methods. Main Modules:- 1. User Module: In this module, Users are having authentication and security to access the detail which is presented in the ontology system. Before accessing or searching the details user should have the account in that otherwise they should register first. 2. Secure DeDuplication System: To support authorized deduplication, the tag of a file F will be determined by the file F and the privilege. To show the difference with traditional notation of tag, we call it file token instead. To support authorized access, a secret key kp will be bounded with a privilege p to generate a file token. Let ϕ′ F;p = TagGen(F, kp) denote the token of F that is only allowed to access by user with privilege p. In another word, the token ϕ′ F;p could only be computed by the users with privilege p. As a result, if a file has been uploaded by a user with a duplicate token ϕ′ F;p, then a duplicate check sent from another user will be successful if and only if he also has the file F and privilege p. Such a token generation function could be easily implemented as H(F, kp), where H(_) denotes a cryptographic hash function. 3. Security Of Duplicate Check Token : We consider several types of privacy we need protect, that is, i) unforgeability of duplicate-check token: There are two types of adversaries, that is, external adversary and internal adversary. As shown below, the external adversary can be viewed as an internal adversary without any privilege. If a user has privilege p, it requires that the adversary cannot forge and output a valid duplicate token with any other privilege p′ on any file F, where p does not match p′. Furthermore, it also requires that if the adversary does not make a request of token with its own privilege from private cloud server, it cannot forge and output a valid duplicate token with p on any F that has been queried. 4. Send Key: Once the key request was received, the sender can send the key or he can decline it. With this key and request id which was generated at the time of sending key request the receiver can decrypt the message.

Functional testing of web and mobile applications consists on impersonating a user through some kind of GUI automation technology, being Selenium the most popular solution nowadays. This piece of research progresses in this area by proposing an advanced User Impersonation as a Service (UIaaS) based on cloud technologies. The proposed approach can be seen as a layered service, in which the top tier is a platform called ElasTest, a Software as a Service (SaaS) testing tool aimed to ease end-to-end testing of different kind of applications. The capability to impersonate user provided by ElasTest is built on the top of a Platform as a Service (PaaS) implemented by extending the W3C WebDriver recommendation with advance features to assess web and mobile applications. Finally, an Infrastructure as a Service (IaaS) layer is used as ground technology. This infrastructure has been implemented by leveraging open source lightweight container technologies such as Docker and Kubernetes.

Cloud computing, as a concept, promises cost savings to end-users by letting them outsource their non-critical business functions to a third party in pay-as-you-go style. However, to enable economic pay-as-you-go services, we need Cloud middleware that maximizes sharing and support near zero costs for unused applications. Multi-tenancy, which let multiple tenants (user) to share a single application instance securely, is a key enabler for building such a middleware. On the other hand, Business processes capture Business logic of organizations in an abstract and reusable manner, and hence play a key role in most organizations. This paper presents the design and architecture of a Multi-tenant Workflow engine while discussing in detail potential use cases of such architecture. Primary contributions of this paper are motivating workflow multi-tenancy, and the design and implementation of multi-tenant workflow engine that enables multiple tenants to run their workflows securely within the same workflow engine instance without modifications to the workflows.

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.

Abstract--Due to risk in service availability failure and the possibilities of malicious insiders in the single cloud, a movement towards “Multi-clouds” has emerged recently. In general a multi-cloud security system there is a possibility for third party to access the user files. Ensuring security in this stage has become tedious since, most of the activities are done in network. In this paper, an enhanced security methodology has been introduced in order to make the data stored in cloud more secure. Duple authentication process introduced in this concept defends malicious insiders and shields the private data. Various disadvantages in traditional systems like unauthorized access, hacking have been overcome in this proposed system and a comparison made with the traditional systems in terms of performance and computational time have shown better results.

Public-key cryptosystems produce constant-size cipher texts with efficient delegation of decryption rights for any set of cipher texts. One can aggregate any set of secret keys and make them as compact as a single key. The secret key holder can release a constant-size aggregate key for flexible choices of cipher text set in cloud storage. In KAC, users encrypt a message not only under a public-key, but also under an identifier of cipher text called class. That means the cipher texts are further categorized into different classes. The key owner holds a master-secret called master-secret key, which can be used to extract secret keys for different classes. More importantly, the extracted key have can be an aggregate key which is as compact as a secret key for a single class, but aggregates the power of many such keys, i.e., the decryption power for any subset of cipher text classes. The key aggregate cryptosystem is enhanced with boundary less cipher text classes. The system is improved with device independent key distribution mechanism. The key distribution process is enhanced with security features to protect key leakage. The key parameter transmission process is integrated with the cipher text download process.
