| 摘 要： | PDA作为一种手持设备,面临着众多的安全问题.文中利用可信计算思想构造了可信PDA的体系结构与安全机制.首先提出了一种带数据恢复功能的星型信任结构,其在安全性、效率及可靠性等方面较TCG的链式信任结构都有很大提升.在此基础上,进一步使用总线仲裁等技术构造了可信PDA的体系结构模型.文中还提出并实现了针对可信PDA嵌入式操作系统的安全增强、基于可信PDA平台的可信网络连接(TNC)以及SD卡全卡加密等新的安全技术与方法.在此基础上,给出一种可信PDA的原型系统.经过实验验证,这款可信PDA在各方面都达到了可信计算平台的技术要求.

| Abstract: | PDA as a handheld device,faced with a number of security issues.This paper describes the Trusted PDA architecture and security mechanism by using the method of Trusted Computing.Firstly this paper proposes a star-style chain of trusted structure with data recovery functions,and it owns more safety,efficiency and reliability than the TCG trust structure.On this basis,the further use of technologies such as bus arbitration system constructs a trusted structural model of PDA.The paper also proposes and impleme... |
