  • Cipher message assist instructions
    Patent number: 7257718
    Abstract: A method, system and program product for enciphering or deciphering storage of a computing environment by specifying, via an instruction, a unit of storage to be enciphered or deciphered. The unit of storage to be enciphered or deciphered includes a plurality of pages which may be operated on in a chaining operation.
    Type: Grant
    Filed: May 12, 2003
    Date of Patent: August 14, 2007
    Assignee: International Business Machines Corporation
    Inventors: Shawn D. Lundvall, Ronald M. Smith, Sr., Phil Chi-Chung Yeh
  • Message digest instructions
    Patent number: 7159122
    Abstract: A method, system and computer program product for digesting data in storage of a computing environment. The digesting computes a condensed representation of a message or data stored in the computer storage. A COMPUTE INTERMEDIATE MESSAGE DIGEST (KIMD) and a COMPUTE LAST MESSAGE DIGEST (KLMD) instruction are disclosed which specify a unit of storage to be digested by a secure hashing algorithm.

  • Security message authentication control instruction
    Publication number: 20040230796
    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.
