Software requirements

Before you install and configure InfoSphere® Guardium Data Encryption, make sure that your environment meets the following minimum software requirements.

InfoSphere Guardium Data Encryption works with all supported releases of DB2® and IMS™.

InfoSphere Guardium Data Encryption requires that Integrated Cryptographic Service Facility (ICSF) is active. The ICSF version that is required depends on the platform and the cryptographic hardware that is installed.

In addition to being active, the ICSF version must support the secure key device on the specific platform.

On z10™ processors that support the Crypto Express3 coprocessor with CP Assist for Cryptographic Function (CPACF protected key), z/OS® 1.9 or later is required with ICSF release HCR7770 or later.

For z10 systems without a CEX2C card, encryption can be implemented with the ICSF release HCR7751.

To use clear keys on the IBM System z z890 or IBM System z z990 processor with OS/390® Version 2 Release 10 or later, the following software is required:

IMS and DB2 Data Encryption Tool PTF UK00049 (APAR-PQ94822).
To ensure that ICSF also provides clear key support, the following FMIDs must be updated:
- HCR770A with PTF UA15677
- HCR770B with PTF UA15678
- HCR7720 with PTF UA15679
- HCR7730 (which has the clear key PTF incorporated) or later
