Design And Implementation Of A Trusted Electronic Signature System

With the rapid development of global information, the issue of information security is concerned increasingly. The traditional techology of information security has increased the complexity of the system,and the expense of operating and maintaining as well, firewall, intrusion detection and anti-virus software for instance.As a result,its development encountered a bottleneck.Then, the concept of trusted computing based on hardware support is introduced into people’s mind.With combining the key technology of network security and cryptography,it forces on the hardware and the sofeware base of system to protect the system security.In this paper, it will introduce the hardware structure of the trusted cryptographic support platform and TPM in further,and will discuss several main functions of the platform service module such as the platform integrity metric, trust chain transferring, platform integrity proof and security storage at first.Then, it will pay a detail analysis to the structure and principle of the simulation package in order to complete the simulation of the trusted electronic signature successfully.In final, the state of all functions running on tpmmanager sofeware which based on VMware Workstation 6.5-7.0 are shown to be normal.
