Trusted Execution Environment and Linux- A Survey

摘要

Improving security and user integrity in Linux operating system has always been a challenging task. One method of improving security is by implementing the Trusted Execution Environment (TEE). While Trusted Computing and Linux may seem antithetical on the surface, Linux users can benefit from the security features, including system integrity and key confidentiality, provided by Trusted Computing. Thisis a study on the key concepts and software components that are required to enable the use of the TEE. Also the existing implementation of TEE by IBM, Intel and TCG has been discussed here.
