ABSTRACT:
Systems, methods and program products for a first central processing unit (CPU) configured to perform tasks that do not require manipulation of sensitive information and a second CPU that is configured to perform tasks that manipulate the sensitive information on behalf of the first CPU. The first CPU and the second CPU can communicate through a secure interface. The first CPU cannot access the sensitive information within the second CPU.
