IBM 4765 PCIe Cryptographic Coprocessor

Performance measurements

IBM conducted performance tests in its lab using the following criteria:

The following data shows performance measurements based on the criteria shown above using selected CCA verbs. Performance can be affected by many factors. IBM does not guarantee that you will achieve the same performance numbers given in this table. This information is provided 'AS IS' and without warranty, express or implied. By quoting a particular key length or cryptographic algorithm, one may not conclude that IBM implies the key length or cryptographic algorithm are adequate and can therefore be used safely. The cryptographic functions described below may not be available in all countries and may be subject to export regulations.

The following document summarizes the performance data in text and graphical form:

News for current customers


New product release CCA 5.0 for Linux on IBM z Systems™ now available effective July 2015. See Overview page for additional information.

IBM PureFlex™ customers can purchase an IBM 4765 as an add-on feature as of September 10, 2013. See CCA Release 4.3.5 for more information.

New product release CCA 4.3.8 for IBM 4765 now available on IBM AIX operating system effective June 2013. See Library page for additional information.

As of February 19, 2013, the 4765 hardware security module (HSM) is validated to meet the MEPS (Méthode d'Évaluation des Produits Securitaire "bancaires") approval scheme used by Cartes Bancaires (CB) banking ecosystem. This standards certification allows the 4765 HSM to be used by CB member banks on their dedicated payment networks.

New product release for IBM 4765 now available on IBM ServerProven System x servers, effective July 2012. This release includes support for the SLES 11.2 O/S. Support is also included for controlling the wrapping of a key with a weaker key, DUKPT for encryption and MAC keys, ciphertext translation, and AMEX enhanced CSC generation and PIN/Change Unblock.

Important notice to ECC users: This release contains important security-related changes for ECC users. See Release 4.3.4 information for details.

Effective December 2011, new add-on features are being offered for the IBM 4765 on System x to support additional operating systems. See the IBM 4765 software updates page.

On System z, the coprocessor is available as Crypto Express3 and is also available for Linux.
