With the rapid development and popularization of mobile intelligent terminal devices, mobile intelligent terminals have become an indispensable part of people's study, work and life. The security issue about intelligent terminals is getting more and more attention. How to build a secure and trusted intelligent terminal environment is an urgent problem to be studied. Trusted computing technology is introduced in android-based mobile intelligent terminal. Trusted platform module is embedded into the intelligent terminal platform. Through the construction of the static credible chain, the hardware and the system are guaranteed to be secure and credible. Through the construction of the dynamic credible chain, the application installation and system operation process are guaranteed to be secure and credible. Through the transmission of the credible chain, it can ensure that the intelligent terminal system is safe and credible from booting to the whole running process. Thereby a secure and trusted intelligent terminal platform has been built. The experimental results show that the proposed method is reasonable and feasible. It can guarantee the operation of mobile intelligent terminal devices in a secure and trusted environment. It has certain promotion significance for promoting the development of terminal equipment in information security.
