Open publisher page 0 citations

Abstract

As a new type of dynamic infrastructure-less networks,mobile Ad Hoc networks are vulnerable to many types of attacks.So the key agreement protocol with mutual authentication between communicators is crucial for the security of MANETs.A key agreement scheme with mutual authentication,which is based on bilinear pairing,is proposed in this paper.This scheme implements two key agreement protocols.One is for the anonymous group member authentication among neighbors.The other is for the session key agreement with mutual authentication.The security and computation cost are analyzed.The results show that the scheme proposed in this paper is very suitable for MANETs.
