Research on High Performance Secure Mobile Terminal Based on Offline Business Detection

In order to prevent users from fake, this paper establishes a highly secure mobile terminal architecture based on ARM TrustZone, and analyzes the communication and memory sharing between trusted execution environment and common execution environment. The trust model of user operation is established, then propose a self _destruction mechanism of mobile equipment based on chip materials to detect fraudulent use, finally put forward the judgment method of mobile terminal reliability data based on detection. The experimental results show that the smaller of the threshold, the higher the frequency for user inputting fingerprint.
