Research on application of trusted technology in localized embedded platform

Abstract： The security threats of localized embedded platforms are still severe. In order to improve the security and controllability of localized platforms, the application of trusted technology is critical. This article uses a trusted platform control module(TPCM) on a localized embedded platform based on the Godson 2K-1000CPU, using trusted boot, trusted software base, trusted file storage and I/O ports. Technology such as trusted access realizes the trusted operation of the localized embedded platform. The TPCM trusted module is implemented based on the CCP903T cryptographic chip. This platform has been tested and put into use in a security project, leaving a reference for the application of trusted technology in the localization platform and the formation of standardization.
