IBM 4765 cryptographic coprocessor

This paper provides an overview of the 4765 cryptographic coprocessor hardware and firmware architecture, its key design features, and an overview of the IBM System z® secure software stack. The hardware for the 4765 solution is shared across all IBM server platforms offering cryptographic hardware acceleration in a highly programmable coprocessor environment designed to meet the most stringent security requirements. Its internal hardware and firmware can be easily updated to meet new security standards and requirements, as well as new customer-specific functionality. It allows updates and customization to be executed with zero downtime, meeting the highest standard of reliability and availability. Standard cryptographic functions and specialized banking and financial functions are supported.
