摘要：
A method and apparatus for an independent operating system that prevents certain classes of computer attacks. Instruction decryption is performed on an existing instruction set for a processor. The processor architecture limits the impact on processor execution timing. The instruction execution timing is not altered in the processor core and any additional processing is overlapped into existing operations.
