摘要: A microprocessor is provided with a method for decrypting encrypted instruction data into plain text and securely executing the same. The includes master key register file comprising plurality of keys. Selection logic circuitry in selects combination at least two Key expansion performs mathematical operations on selected keys to generate decryption having long effective length. Instruction an efficient operation decrypt data.
