基于身份的认证密钥协商协议的改进
IMPROVEMENT OF ID-BASED AUTHENTICATED KEY AGREEMENT PROTOCOL
摘要
Abstract
To solve the security problem in existing ID-based authenticated key agreement protocol,in this paper we propose an improved ID-based authenticated key agreement protocol.The protocol uses bilinear pairing operation method,combines the temporary and long-term private keys of both users sides to calculate the final session key,and solves the problem of PKG-forward security in previous protocol,the problem caused by singly depending on the temporary or long-term private keys,and the problem of known temporary session key leakage attacks.Based on ensuring the correctness of the improved protocol,we analyse the security attribute and the performance of the improved protocol,and carry out formal analysis on the protocol with SVO logic,as well as verify the authentication property and security of the improved protocol.Results show that it satisfies all the security requirements of an ID-based authenticated key agreement protocol.Comparing with other existing similar protocols,it has better safety attribute and higher computational efficiency.关键词
