摘要：In a microprocessor, a program key for decrypting a program and a data keyfor encrypting/decrypting data processed by the program are handled as
cryptographically inseparable pair inside the microprocessor, so that it becomes possiblefor the microprocessor to protect processes that actually execute the program, withoutan intervention of the operating system, and it becomes possible to conceal secretinformation of the program not only from the other user program but also from theoperating system.
