IBM 4769

The IBM 4769, also known as the IBM PCI Cryptographic Coprocessor, is a hardware security module (HSM) designed to provide tamper-resistant cryptographic processing and key storage. It is a PCI-based card intended for use in servers and other computing systems requiring high levels of security.

The primary function of the IBM 4769 is to perform secure cryptographic operations, such as encryption, decryption, digital signature generation, and hashing. It is specifically designed to protect sensitive cryptographic keys from unauthorized access, modification, or disclosure. This protection is achieved through a combination of physical security measures and secure software implementations.

The IBM 4769 adheres to industry standards for HSMs and cryptographic security. It often provides features such as key management, role-based access control, and audit logging to ensure the integrity and confidentiality of cryptographic operations and keys. The coprocessor is often used in applications such as financial transactions, digital rights management, and secure web servers where high security and compliance requirements exist.

The IBM 4769 typically includes secure memory for storing cryptographic keys and firmware, as well as hardware acceleration for cryptographic algorithms. It is designed to resist physical attacks and tampering, making it suitable for use in highly secure environments. Software interfaces and drivers are provided to allow applications to access the cryptographic functions of the coprocessor. Its predecessor was the IBM 4758.
