Efficient and secure certificateless key agreement protocol
Xiaolei Dong
Abstract
In the area of network information security,key agreement is essential between servers and clients.To overcome the key escrow property of identity-based cryptography,proposed certificateless public key cryptography,it combined the advantages of the traditional PKI and the identity-based cryptography.This paper proposed a new certificateless two-party key agreement protocol using pairing operation in elliptic curves,it only required each party to compute one pairing.Proved its security in ECK(extended Canetti-Krawczyk) model.Compared with existing certificateless protocols,the newly proposed key agreement protocol has better security and efficiency.
