IBM 4764

The IBM 4764 Cryptographic Coprocessor is a secure cryptoprocessor that performs cryptographic operations used by application programs and by communications such as SSL private key transactions associated with SSL digital certificates.

The HSM has been certified to meet FIPS 140-2 Level 4 security requirements.

Applications may include financial PIN transactions, bank-to-clearing-house transactions, EMV transactions for integrated circuit (chip) based credit cards, and general-purpose cryptographic applications using symmetric key algorithms, hashing algorithms, and public key algorithms.

The operational keys (symmetric or RSA private) are generated in the coprocessor and are then saved either in a keystore file or in application memory, encrypted under the master key of that coprocessor.

The successor to the 4764 was introduced on each of the IBM server platforms between 2009 and 2011: This cryptography-related article is a stub.
