INSTRUCTION AND LOGIC TO PROVIDE A SECURE CIPHER HASH ROUND FUNCTIONALITY

摘要

Instruction and logic provide the cryptographic Hash algorithms circle function of safety. Some embodiments include a kind of processor comprising: decoder stage instruction is decoded safe cryptographic Hash algorithms, and first instructs specified source, and one or more cipher key operation numbers. Processor execution unit executes the cryptographic Hash algorithms circle iteration of one or more safety in response to decoded instruction in the data in source, and using one or more cipher key operation numbers, and the result of store instruction is in destination register. The iteration for specifying safe cryptographic Hash algorithms circle Feistel cryptographic algorithms of one embodiment uses such as DES or TDES. In one embodiment, the result of instruction can cross over one group of process resource from request load balance generating resource assignation request.
