You need to talk to your site support group and find out if any encryption software is installed at your site. Encryption software is not free (see below for IBM"s offering), so not all sites have purchased the software. ICSF is hardware that support encryption but it won't invoke itself -- software has to invoke ICSF.
The Encryption Facility for z/OS (Program number: 5655-P97), first introduced in 2005, is a host based software solution designed to encrypt sensitive data before transferring it to tape for archival purposes or business partner exchange. In addition to writing encrypted data to tape, the Encryption Facility for z/OS can also be used to produce encrypted data written to disk and other removable media.
Encryption Facility for z/OS consists of two priced optional features:
The Encryption Services feature supports encrypting and decrypting certain file formats on z/OS. This can allow you to transfer them to remote sites within your enterprise, transfer them to partners and vendors, and archive them. The Encryption Services feature supports both the System z format (originally introduced in Encryption Facility for z/OS V1.1) and the OpenPGP format (new with Encryption Facility for z/OS V1.2). The System z format supports hardware-accelerated compression before encryption.
The DFSMSdss Encryption feature enables the encryption of DFSMSdss dump data sets. This feature supports hardware-accelerated compression before encryption to tape.
