摘　　要：针对当前信息安全认证中存在的终端可信问题,提出基于TPM的CPK信息安全认证技术,从而实现从终端平台到上层应用的环境可信。首先介绍TPM及其功能和CPK认证技术,然后为基于TPM的CPK认证技术体系构建了总体技术架构,通过对TPM的结构进行改进,使其功能得到了增强和封装,并为该认证技术设计了相应的认证流程,最后以飞行器应用程序的升级为例,对该认证技术的认证过程进行了具体说明。Aiming at the terminal trusted problem existing in the current information security authentication, the information security authentication of the combined public key （CPK）based on the trusted platform model （TPM） is presented to realize the environment trustment from the terminal platform to the upper formation application. TPM functions of and CPK authentication technology are introduced. An overall technique arckiteeture is built for the CPK information security authentication based on TPM. The function was enhanced and sealed through improvement of TPM structure. The corresponding au- thentication flow for the authentication technique was designed. Taking the promotion of the aircraft application procedure as the example, the authentication process of this authentication technology is elaborated.
