Abstract (in Japanese) (See Japanese page) 
(in English) It emerges that the use of security systems which separate device resources into Trusted Execution Environment (TEE) and Rich Execution Environment (REE) by adopting TrustZone supported by ARM microcontrollers. The key idea is to prevent attackers to access to sensitive data by limiting the processing of the sensitive data shall be on TEE while other processing can be done on REE. To evaluate the security of the software architecture of TEE, we implemented an open source TEE, OP-TEE, on a SoC for automobile and several test applications. Our conclusion is that even if we use sensitive data only within TEE the data can be compromised if Trusted Application (TA) run on TEE contains some vulnerabilities.
