Transaction Security System extensions to the Common Cryptographic Architecture
Donald Barton Johnson, G. M. Dolan · IBM Systems Journal · 1991
A well-designed application program interface for a line of cryptographic products simplifies customer use of cryptographic services by helping to ensure compliance with national and international standards and by providing intuitive high-level services that may be implemented on disparate systems. The Common Cryptographic Architecture is IBM's strategic cryptographic architecture. The Transaction Security System implements the Common Cryptographic Architecture in full. Furthermore, the Transaction Security System has implemented extensions to the architecture to address additional customer requirements. This paper gives the design rationale for some of the additional cryptographic functionality in the Transaction Security System beyond that mandated by the Common Cryptographic Architecture.
