ABSTRACT:
A method and apparatus for restricting the execution of security sensitive instructions. A first security identification (ID) is associated with each of a plurality of instructions or a set of instructions that are to be executed by a processor. Software code running on the processor requests to execute at least one of the plurality of instructions or set of instructions. The processor obtains a second security ID associated with the software code running thereon and compares the second security ID with the first security ID. The processor executes the requested instruction or set of instructions providing that the second security ID matches the first security ID.
