ABSTRACT:
An apparatus for performing cryptographic operations. The apparatus includes an x86-compatible microprocessor that has fetch logic, algorithm logic, and execution logic. The fetch logic is configured to receive a single, atomic cryptographic instruction as one of the instructions in an application program executing on the x86-compatible microprocessor. The single, atomic cryptographic instruction prescribes an encryption operation and one of a plurality of cryptographic algorithms. The algorithm logic is operatively coupled to the single, atomic cryptographic instruction. The algorithm logic directs the x86-compatible microprocessor to execute the encryption operation according to the one of a plurality of cryptographic algorithms. The execution logic is operatively coupled to the algorithm logic. The execution logic executes the encryption operation. The execution logic includes a cryptography unit for executing a plurality of cryptographic rounds required to complete the encryption operation.
