David Cerdeira, Nuno Santos, Pedro Fonseca, Sandro Pinto
2020 2020 IEEE Symposium on Security and Privacy (SP)  
Hundreds of millions of mobile devices worldwide rely on Trusted Execution Environments (TEEs) built with Arm TrustZone for the protection of security-critical applications (e.g., DRM) and operating system  ...  To this end, we present a security analysis of popular TrustZone-assisted TEE systems (targeting Cortex-A processors) developed by Qualcomm, Trustonic, Huawei, Nvidia, and Linaro.  ...  INTRODUCTION Trusted Execution Environments (TEE) are a key security mechanism to protect the integrity and confidentiality of applications.  ...
