The IBM 4758 PCI Cryptographic Coprocessor is a secure cryptoprocessor
Secure cryptoprocessor
A secure cryptoprocessor is a dedicated computer on a chip or microprocessor for carrying out cryptographic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance....

Microprocessor
A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

Data processing
Computer data processing is any process that a computer program does to enter data and summarise, analyse or otherwise convert data into usable information. The process may be automated and run on a computer. It involves recording, analysing, sorting, summarising, calculating, disseminating and...

IBM supplies two cryptographic-system implementations, and toolkits for custom application development:
  • The PKCS#11
    PKCS11
    In cryptography, PKCS #11 is one of the family of standards called Public-Key Cryptography Standards , published by RSA Laboratories, that defines a platform-independent API to cryptographic tokens, such as Hardware Security Modules and smart cards...

    , version 2.01 implementation creates a high-security solution for application programs developed for this industry-standard API.
  • The IBM Common Cryptographic Architecture implementation provides many functions of special interest in the finance industry and a base on which custom processing and cryptographic functions can be added.


As of June 2005, the 4758 was discontinued and was replaced by an improved, faster model called the IBM 4764
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. Each coprocessor includes a tamper-responding hardware security...
