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 aims at the existing problems of Needham-Schroeder public key authentication protocol, improves the protocol by using the related functions of TPM, and proposes the NSPK authentication protocol based on TPM. Which solves the security flaw of the attacker’s counterfeit entity A and entity B sharing the secret data, and improves the security remarkably.
