An Improved Authenticated Multiple-key Agreement Protocol

Chameleon-Based Deniable Authenticated Key Agreement Protocol

As a useful means of safeguarding privacy of communications, deniable authentication has received much attention. A Chameleon-based deniable authenticated key agreement protocol is presented in this paper. The protocol has following properties. Any one of the two participants can’t present a digital proof to convince a third party that a claimed agreement has really taken place. Once a forgery ...

Identity Based Authenticated Group Key Agreement Protocol

An important and popular trend in modern computing is to convert traditional centralized services into distributed services spread across multiple systems and networks. One-way function trees can be used to extend two-party Key Agreement protocols to n-party protocols. Tree-based Group Diffie-Hellman [17] is one such protocol. This paper proposes the first Identity based Group Key Agreement pro...
