With the development of computer science and technology, current secure operating systems failed to respond to many new security challenges. Trusted operating system (TOS) is proposed to try to solve these problems. However, there are no mature, unified architectures for the TOS yet, since most of them cannot make clear of the relationship between security mechanism and the trusted mechanism. Therefore, this paper proposes a double-system architecture (DSA) for the TOS to solve the problem. The

Furthermore, we proposed the Trusted Information Channel (TIC) to protect the information flow between TS and SS. In a word, the doublesystem architecture we proposed can provide reliable protection for the OS through the SS with the supports provided by the TS.
