Current automotive software is evolving to integrate extension software with control software. Software integration increases the complexity of software and can cause system fault that threats safety of automobile. To solve this problem, extension software should be isolated from control software. However, this isolation alone is not sufficient to prevent extension software from faulting control software due to the lack of secure device access. In this paper, we propose a secure automotive software platform that has secure device access method with TrustZone. Our method restricts a direct access of the extension software and supports multicore processors. Measured overhead of our platform shows less than 1% degradation, and the maximum bandwidth of device access is achieved up to 5MB/s.
