CRYPTOGRAPHY ARCHITECTURE FOR INFORMATION SECURITY

Information being transferred from point to point over a public communications carrier or stored on portable media can be protected, by the use of cryptography, from accidental or intentional disclosure. Control functions are required to ensure synchronization of the process. In a communications environment, the control functions become logically part of the network architecture. IBM's Systems Network Architecture (SNA) has been extended to allow the use of cryptography when sensitive information is being processed. Architectural similarities for the file environment are discussed.
