摘要
本文针对Needham-Schroeder公钥认证协议存在的问题,利用TPM的相关功能对协议进行了改进,提出了基于TPM的NSPK认证协议。解决了攻击者仿冒实体A与实体B共享秘密数据的安全缺陷,使其安全性有了显著提高。
This paper analyses the problems that exists in the Needham-Schroeder public key authentication protocol, and proposes an improved NSPK protocol based on TPM.In the improved protocol,the previous flaws that the attackers may impersonate A＇s response and share the sensitive data with B is solved.Consequently,the security of the protocol can be strengthened.
