A group secure key generation and transfer protocol based on ICMetrics

Secure group communications are more prone to attacks as compared to the conventional one to one communication. Every client in a group can be seen as a single source of attack, therefore it is important to design a robust security scheme that will protect all the individual clients and hence the entire group. In this paper a novel security architecture has been presented, that provides a secure group key generation and transfer protocol that is based on ICMetrics. The salient features of the protocol include a single collaborative key generation scheme that is initiated through client authentication. Also provided is a rekeying procedure that is important in maintaining the freshness of the key and offers perfect forward secrecy. The above features are based on the use of ICMetrics to provide a security protocol that is scalable and secure. The presented protocol has been simulated for varying group population sizes using C++ and Maple. The resulting running times for various stages of the protocol have been studied.
