Abstract:
A method, system and computer program product for computing a message authentication code for data in storage of a computing environment. An instruction specifies a unit of storage for which an authentication code is to be computed. An computing operation computes an authentication code for the unit of storage. A register is used for providing a cryptographic key for use in the computing to the authentication code. Further, the register may be used in a chaining operation.
