Security in Group Conference Protocol (SGCP)

The technology of digital conference has opened up a new area of research and application to computer networks in industry. It can be used in a board meeting, scientific discussion or in virtual classrooms, through the computers connected by IP networks. To protect conversations from eaves dropping, a common conference key agreement protocol is required. Conference key protocol secures the discussion session and data among multiple conferees engaged in common goal of communication. Numerous works have been carried out in providing secured conference, but most of the works concentrate on an efficient key exchange protocol to prevent malicious users to attempt to play the proxy role or delay or destruct the conference environment. This paper proposes a novel approach of unique dynamic ID based key exchange protocol using Diffie-Hellman algorithm, which possesses the property of fault-tolerance secured session, dynamic ID key generation and key exchange methods.
