Analysis and Improvement of Authenticated Key Agreement Protocol Based on Signcryption
摘要
Abstract
The key establishment protocol called LLH can not resist impersonation attack. Aiming at this problem, an improved protocol based on signcryption is proposed. It uses elliptic curve cryptosystem technology under the computational Diffie-Hellman assumption, combines authentication and session key and implements the functions of mutual authentication and key confirmation, so that the security is enhanced. Theoretical analysis results show that the proposed protocol has strong security features and can be resistant to impersonation attack.关键词
