Abstract

ID-based protocols are used to establish session keys with identity information of principals.An ID-based key exchange protocol was proposed based on the difficulty of computing a discrete logarithm problem,and the performance and security of the proposed protocol were analyzed.The analysis shows that the proposed protocol has better performance and it can satisfy the security requirements of the two-party key exchange protocol.
