Abstract :
Nowadays smart devices´ safety problems directly influence the users´ private information security, especially the assets appeared in the critical applications when doing some sensitive operations. So the sensitive applications´ securities in smart devices have become a problem demanding prompt solution in current environment that malicious softwares all over the place. This paper presents a design and implementation of a software framework with a Dual Operating System - a GPOS and a secure OS. In the framework, the secure OS acts as a platform which is dedicated to providing specific security services, and the GPOS is used to satisfy users´ application requirements. The proposed framework´s design and implementation should be based on ARM TrustZone Processor, or the other processors that have the similar features with spatial isolation functions. The approach proposed in this paper is implemented correctly with the SMDK210 development board. The framework is suitable for many applications such as secure payment and DRM.
