ABSTRACT:
Methods and apparatus are provided for an entity such as a CPU to efficiently call a cryptography accelerator to perform cryptographic operations. A function call causes the cryptography accelerator to execute multiple cryptographic operations in a manner tailored for specific processing steps, such as steps during a handshake phase of a secured session. The techniques provide efficient use of hardware processing resources, data interfaces, and memory interfaces.
