The project implements the fundamental establishment of group key through distributed and collaborative approach for a dynamic peer group. The main function of the project is to provide secured communication through key authentication process. Three Interval Based Re-Keying algorithms are used to eliminate the individual re-keying approach in which re-computation of the key is performed after each joining and leaving of the member. The three interval based re-keying algorithms are 1. Rebuild Algorithm 2. Batch Algorithm 3. Queue-Batch Algorithm ....etc

Abstract
Cloud computing is an emerging computingparadigm in which resources of the computing infrastructureare provided as services over the Internet. As promising as it is,this paradigm also brings forth many new challenges for datasecurity and access control when users outsource sensitive datafor sharing on cloud servers, which are not within the sametrusted domain as data owners. To keep sensitive user dataconfidential against untrusted servers, existing solutions usuallyapply cryptographic methods by disclosing data decryption key ....etc

Abstract
In mobile ad hoc networks, due to unreliable wireless
media, host mobility and lack of infrastructure, providing secure
communications is a big challenge in this unique network environment.
Usually cryptography techniques are used for secure
communications in wired and wireless networks. The asymmetric
cryptography is widely used because of its versatileness (authentication,
integrity, and confidentiality) and simplicity for key distribution.
However, this approach relies on a centralized framework
of public key infras ....etc

Abstract
Three-party authenticated key exchange protocol(3PAKE) is an important cryptographic technique for securecommunication which allows two parties to agree a new securesession key with the help of a trusted server. In this paper, weproposed a new three-party authenticated key exchange protocolwhich aims to achieve more efficiency with the same security levelof other existing 3PAKE protocols. Security analysis and formalverification using AVISPA tools show that the proposed protocolis secure against various known attacks. Comparin ....etc

Abstract”
Wireless broadcast is an effective approach to disseminate data to a number of users. To provide secure access to data in wireless broadcast services, symmetric key-based encryption is used to ensure that only users who own the valid keys can decrypt the data. Regarding various subscriptions, an efficient key management to distribute and change keys is in great demand for access control in broadcast services. In this paper, we propose an efficient k ....etc

An Efficient Time-Bound Hierarchical Key Management Scheme for Secure Broadcasting-IEEE TRANSACTIONS ON DEPENDABLE AND SECURE COMPUTING, VOL. 5, NO. 2,
-java
Abstract—
In electronic subscription and pay TV systems, data can be organized and encrypted using symmetric key algorithms according to predefined time periods and user privileges and then broadcast to users. This requires an efficient way of managing the encryption keys. In this scenario, time-bound key management schemes for a hierarchy were proposed by Tzeng and Chien in ....etc
