Abstract

Trusted Execution Environment (TEE) is an important part of the security architecture of modern mobile devices, but its secure interaction process brings extra computing burden to mobile devices. This paper takes open portable trusted execution environment (OP-TEE) as the research object and deploys it to Raspberry Pi 3B, designs and implements a benchmark for OP-TEE, and analyzes its program characteristics. Furthermore, the application execution time, energy consumption and energy-delay product (EDP) are taken as the optimization objectives, and the central processing unit (CPU) frequency scheduling strategy of mobile devices is dynamically adjusted according to the characteristics of different applications through the combined model. The experimental result shows that compared with the default strategy, the scheduling method proposed in this paper saves 21.18% on average with the Line Regression-Decision Tree scheduling model with the shortest delay as the optimization objective. The Decision Tree-Support Vector Regression (SVR) scheduling model, which takes the lowest energy consumption as the optimization goal, saves 22% energy on average. The Decision Tree-K-Nearest Neighbor (KNN) scheduling model with the lowest EDP as the optimization objective optimizes about 33.9% on average.
