8.4 Hardware Cryptographic API Performance

This section provides information on the hardware based cryptographic offload solution IBM 4764
PCI-X Cryptography Coprocessor (Feature Code 4806). This solution will improve the system CPU
capacity by offloading CPU demanding cryptographic functions.

Platform Support
The 4764 Cryptographic Coprocessor provides both cryptographic coprocessor and secure-key
cryptographic accelerator functions in a single PCI-X card. The coprocessor functions are targeted to
banking and finance applications. The secure-key accelerator functions are targeted to improving the
performance of SSL (secure socket layer) and TLS (transport layer security) based transactions. The 4764
Cryptographic Coprocessor supports secure storage of cryptographic keys in a tamper-resistant module,
