改进的ELGamal数字签名的双向认证方案

An Improved Double-Way Authentication Scheme Based on ELGamal's Digital Signature

在文献[1]中,由于需要安全信道确保用户密钥的安全分发,而且用户间的双向认证过程较为复杂,为此提出了一种改进的基于ELGamal数字签名的双向认证方案,该方案可以在不安全的信道上实现密钥的安全分发,而且简化了双向认证的过程,分析表明方案较之先前有了很大的优越性.

Based on complex of secure chanel to distribute secret key and double-way authentication process in literature [1],an improved double-way authentication scheme of ELGamal＇digital signature was proposed.The scheme was able to securely distribute secret key in general channel and was simple to double-way authentication process between users.The analysis shows the scheme is better than prior scheme.
