A Two-Party Certificateless Authenticated Key Agreement Protocol with Provable Security

Abstract

In this paper we propose a two-party certificate less authenticated key agreement scheme which has proven to be secure in the random oracle model. The new protocol is secure as long as each party has at least one uncompromised secret. In addition, the new protocol has higher efficiency than several other strongly secure key agreement protocols(such as Lippold[2], protocol[3], protocol[4]).
