This paper discusses the smart mobile terminal security technology from three aspects: software solutions, solution based on trusted execution environment (TEE) and solution based on secure element (SE). A software-level solution involves security technology used in the rich execution environment. A solution based on TEE involves the system architecture of TEE, isolation technology of TEE and the trusted execution technology. A solution based on SE involves security-enhancement technology based on local SE and cloud of SE. A combination of trusted software and trusted hardware platform guarantees security for smart mobile terminals.
