The IBM 4768 is a high-security, high-throughput member of the IBM hardware security module (HSM) family. This page describes how to order the HSM.
The IBM 4768 is available on IBM Z® family z14® mainframes only, either on z/OS® or Linux® on IBM Z operating systems, ordered as a Crypto feature code (FC) 0893 – Crypto Express 6S (CEX6S).
Note: FC 0893 is available only on z14 mainframes and requires Crypto FC 3863 (CPACF Enablement). CPACF stands for Central Processor Assist for Cryptographic Functions. CPACF is a set of cryptographic instructions providing improved performance through hardware acceleration. Using the cryptographic hardware, you gain security from using the CPACF and CEX6S through in-kernel cryptography APIs and, for Linux on IBM Z, the libica cryptographic functions library. Cryptographic keys must be protected by your application system, as required.
To place an order for the CEX6S feature, contact your IBM Customer Engineer. A minimum of 2 features is required per computer, with a maximum of 16.
