Escrow-free certificate-based authenticated key agreement protocol from pairings
Shengbao Wang, Zhenfu Cao · Wuhan University Journal of Natural Sciences · 2007
Key agreement protocols are essential for secure communications. In this paper, to solve the inherent key escrow problem of identity-based cryptography, an escrow-free certificate-based authenticated key agreement (CB-AK) protocol with perfect forward secrecy is proposed. Our protocol makes use of pairings on elliptic curves. The protocol is described and its properties are discussed though comparison with Smart’s protocol.
