ABSTRACT
Efficient key distribution is an important problem for secure group communications. The communication and storage complexity of multicast key distribution problem has been studied extensively. In this paper, we propose a new multicast key distribution scheme whose complexity is significantly reduced. Instead of using conventional encryption algorithms, the scheme employs MDS codes, a class of error control codes, to distribute multicast key dynamically. This scheme drastically reduces computation load of each group member comp ....etc

Dynamic Balanced Key Tree Management for Secure Multicast Communications - IEEE TRANSACTIONS ON COMPUTERS, VOL. 56, NO. 5, – java

Abstract—
A secure multicast communication is important for applications such as pay-per-view and secure videoconferencing. A key
tree approach has been proposed by other authors to distribute the multicast group key in such a way that the rekeying cost scales with
the logarithm of the group size for a join or depart request. The efficiency of this key tree approach critically depends on whether the ....etc

EFFICIENT KEY GENERATION FOR LARGE & DYNAMI MULTICAST GROUPS



1. Introduction

1.1 About the Project
The Efficient Key Agreement for Large and Dynamic Multicast Groups provides
an efficient way of Group key Agreement in terms of Scalability and Authenticity between the Sub group members and to other group members in the network. The Existing system have the drawbacks such as the Group Controller takes all responsibilities of key generation, re keys ge ....etc

AKA stands for the Authentication and Key Agreement security protocol. It is a mechanism which performs authentication and session key distribution in Universal Mobile Telecommunications System (UMTS) networks. AKA is a challenge-response based mechanism that uses symmetric cryptography. AKA is typically run in a UMTS IM Services Identity Module (ISIM), which resides on a smart card like device that also provides tamper resistant storage of shared secrets.

Distributed Collaborative Key Agreement and Authentication Protocols for Dynamic Peer Groups (Java, VB.NET)
IEEE/ACM Transactions on Networking, Vol. 14, No. 2,
Abstract: We consider several distributed collaborative key agreement and authentication protocols for dynamic peer groups. There are several important characteristics which make this problem different from traditional secure group communication. They are distributed nature in which there is no centralized key server, collaborative nature in which the group key is contributory (i.e., ....etc

SCAMP : SCAlable Multicast Protocol for Communication in Large Groups


This report proposes a new scalable multicast protocol for communication within a large group over Internet. There are many existing and new applications in which the groups involved are very large. An example would be Video-conferencing amongst a large and widely distributed group. The members of such a group can be spread across the entire Internet with no uniformity in their pattern of distribution. In such applications, there will be one or at most a few sources and ....etc
