Mutual authentication and key agreement in NS2

Electronic commerce transactions on mobile devices develops rapidly and are implemented on Internet or wireless networks. To achieve secure communication, mutual authentication with key agreement schemes are necessary and inspiring. Schemes can be constructed from passwords, traditional public key cryptography, and identity-based cryptography. And identity-based mutual authentication with key agreement schemes based on elliptic curve cryptography are preferable. This paper presents a secure and efficiency identity-based mutual authentication with key agreement scheme for mobile client-server environment.
