IBM 4764 PCI-X Cryptographic Coprocessor


On May 24, 2011, IBM announced that the IBM 4764-001 Cryptographic Coprocessor and its associated feature code 1008 (battery-replacement kit) will be withdrawn from marketing effective December 31, 2011 (IBM United States Withdrawal Announcement 911-129).

On or after the effective date for the withdrawal of this offering, you can no longer order this product directly from IBM. However, IBM will continue to honor contracts until expiration or termination of the current contract. You may be able obtain the product on an as-available basis through IBM Business Partners.

Effective December 31, 2011, Feature code 1008 can no longer be used to order battery replacement kits. Battery replacement kits and multi-battery packs are now available for ordering as part numbers.

To order the battery-replacement kit, or the multi-battery pack, customers in:

FIPS PUB 140-2 certified electronics and cryptographic algorithms

The rigorous FIPS PUB 140-2 Security Requirements for Cryptographic Modules (PDF, 1.40MB) is the benchmark standard by which cryptographic implementations are measured. The evaluations cover the encapsulated processing subsystem and its specialized cryptographic hardware, code loading, tamper detection and response mechanisms, and the cryptographic algorithms: DES, triple-DES, RSA, DSS, and SHA-1.

The IBM PCI-X Cryptographic Coprocessor has been certified by NIST for IBM System x, IBM System p, IBM System i, and IBM System z.

Coprocessor models and features

The IBM 4764 Model 001 operates on a 3.3-volt PCI-X bus and has two batteries to power the tamper-sensing electronics when no system power is supplied.

Cryptographic software support options

IBM supplies support program code for the IBM CCA cryptographic implementation.

IBM Common Cryptographic Architecture (CCA) provides extensive support of processes based on AES, DES and RSA, including many functions of special interest in the finance industry. A recent addition to CCA includes Elliptic Curve Cryptography (ECC) key generation along with support for digital signature generation and verification using the ECC Digital Signature Algorithm (ECDSA). Another recent addition includes MAC generation and verification using HMAC based on FIPS PUB 198-1, The Keyed-Hash message Authentication Code (HMAC). You can extend the CCA implementation through custom programming described below.

Standard capabilities include PIN processing, Secure Electronic Transaction™ services, data encryption and hashing techniques, and RSA-based public-key cryptography.

The CCA Support Program supports the IBM 4764 PCI-X Cryptographic Coprocessor installed on a ServerProven System x server on the following operating systems:

Note that the ICSF component of z/OS and OS/390 provides support comparable to Release 3.x on the IBM System p, IBM System i and IBM System z servers.

The United States Bureau of Export Administration classifies both Support Programs and the coprocessors as 'Retail Cryptographic Implementations'. Thus, IBM can export these hardware and software products to essentially all customers. (Export restrictions remain in effect for a certain few countries and organizations.)

Custom Programming

Minting of electronic money and electronic postage are examples of critical functions that must run in a highly trustworthy environment. Using toolkits available from IBM under custom contract, you can implement your own applications for the coprocessor, or extend IBM's CCA application. You can make a fast start on your custom application development when you extend CCA using its flexible access-control system and many existing services.

IBM will issue you a unique identifier and certify your code-signing key so that you can sign your own custom coprocessor software. You develop your software using conventional IBM or Microsoft C-language compilers and use the toolkit-provided debugging programs. You or your customers can then load coprocessor software in a normal server environment. Using the PKI-based outbound authentication capabilities of the coprocessor's control program, you can securely administer the coprocessor environment, even from remote locations. Auditors can inspect the coprocessor's digitally signed status response to confirm that the coprocessor remains untampered and running uniquely identified software.
