IBM 4764 PCI-X Cryptographic Coprocessor
IBM Common Name
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,
