Trusted Runtime Environment Building Technology for Mobile Terminals

This paper aims to study the basic theory of the "trusted foundation" of mobile intelligent terminals and build a trusted basic protection scheme that can be used for mobile application protection. Firstly, the ARM hardware structure of Android smartphone is used to study the security architecture of ARM terminal based on trusted technology, and realize the trusted software architecture through Android, analyze the functions at all levels; prove the credibility of Android mobile application APP security startup process, and the specification classifies the proposed trusted structure securely. Secondly, based on the machine code-based integrity measurement in the dynamic credibility of mobile applications, a credible measurement mechanism based on application behavior is studied. The current mobile platform operating environment is based on the integrity of the static integrity measurement mechanism extended to the credibility of the dynamic behavior of the mobile application runtime, combined with the APP using the access control mechanism, by evaluating the execution order access of the APP and related resources, thereby judging whether the application is trusted to build a dynamic and trusted operating environment. Thirdly, by studying the mobile Internet application and the remote authentication technology in trusted computing, the evidence of providing the authentication server with its legitimacy and the credibility of the terminal platform is realized, and the "trustworthiness" of the intelligent terminal is effectively guaranteed.
