IBM 4758
Encyclopedia
The IBM 4758 PCI Cryptographic Coprocessor is a secure cryptoprocessor
implemented on a high-security, tamper resistant, programmable PCI
board. Specialized cryptographic electronics, microprocessor
, memory, and random number generator housed within a tamper-responding environment provide a highly secure subsystem in which data processing
and cryptography
can be performed.
IBM supplies two cryptographic-system implementations, and toolkits for custom application development:
As of June 2005, the 4758 was discontinued and was replaced by an improved, faster model called the IBM 4764
.

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#11PKCS11In 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.

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...
