摘要：
SAM is a processor extension used to protect execution of dedicated programs by preventing data disclosure and program manipulations in a multitasking environment. This paper presents an operating system design based on the Linux kernel for SAM. The design splits the kernel into a very small protected part and an unprotected part used by drivers and high level functions. Using this kernel protected and unprotected programs can be executed in parallel without diminishing the protection. The protection mechanism does not slow down the execution of unprotected programs, since it is only active during the execution of protected programs.
