Abstract

A secure processor (110) assuring application software is executed securely, and assuring only authorized software is executed, monitored nodes, and secure modes of operation. The former executes application software transparently to that software. The latter verifies execution of the application software is authorized, performs any extraordinary services required by the application software, and verifies the processor has obtained rights to execute the content. The secure processor (110) appears hardware-identical to an ordinary processor, with the effect that application software written for ordinary processors can be executed on the secure processor (110) without substantial change, needs only minimal degree of additional hardware over and above those portions appearing hardware identical to an ordinary processor. The secure processor (110) operates without substantial reduction in speed or other resources available to the application software. Functions operating in secure mode might reside in an on-chip non-volatile memory, or might be loaded from external storage with authentication.
