CA Tape Encryption Business-to-Business Processing

CA Tape Encryption allows you to send encrypted tapes to business partners on other z/OS systems or on selected distributed platforms. This is known B2B processing. To decrypt tapes created by CA Tape Encryption, your business partners must do one of the following:

• On z/OS platforms, install and run the CA Tape Encryption base product.
• On Microsoft Windows, Linux, and Sun Solaris platforms, install the Multiplatform Decryption Utility (MDU).

Both the CA Tape Encryption base product and the MDU are available to your business partners free of charge.

What z/OS Business Partners Need to Decrypt B2B Tapes

After you contact your z/OS business partners and agree on the use of CA Tape Encryption, your business partners need to install the free base product, as outlined by the following points:

• Each z/OS partner that wants to process tapes encrypted by CA Tape Encryption should call 1-866-573-3435 and inform the Customer Service Representative that they need to order the free CA Tape Encryption base product.
• The representative will take the necessary information to process and ship the order and provide the required License Managed Product (LMP) key to activate the base product. This license will entitle the z/OS business partner to receive regular maintenance for CA Tape Encryption.

Required Maintenance for z/OS Business Partners

Business partners who install the free CA Tape Encryption base product must plan to keep the product up to date on maintenance using the CA technical support site http://ca.com/support.

What Distributed Business Partners Need to Decrypt B2B Tapes

After you contact your business partners that run distributed systems and agree on the use of CA Tape Encryption, these business partners need to install the Multiplatform Decryption Utility (MDU), as outlined by the following points:

• Business partners who need to process tapes on distributed systems that were encrypted by CA Tape Encryption on the mainframe do not need to order and install the CA Tape Encryption base product.
• These partners should obtain the Multiplatform Decryption Utility (MDU) from the site that creates the encrypted tape.
  • The MDU is delivered as part of the z/OS product install in a ZIP or TAR file format that allows for easy transmission or sharing on a CD-ROM or other media.
  • The MDU files are delivered in a z/OS data set named CAI.CTAPMDU.

Note: For information about the MDU, see the instructions provided in CAI.CTAPMDU member $MDUNDX and the Multiplatform Decryption Utility User Guide.

Required Maintenance for Distributed Business Partners

Business partners who install the MDU on their distributed systems must plan to apply maintenance to the MDU. Maintenance is provided in new TAR and ZIP files delivered to the z/OS product. When maintenance is provided, the new TAR or ZIP file must be sent to the distributed systems that run the MDU. This maintenance must be installed using the instructions provided in the Multiplatform Decryption Utility User Guide.

To insure that proper maintenance is applied, all PTFs that provide maintenance to the MDU include an SMP/E ACTION HOLD.

How You Identify MDU Versions

The ISPF statistics of the members in the CAI.CTAPMDU data set show the date, time and PTF level of the MDU. The maintenance level of the MDU on your target system can be determined by reviewing the readme file delivered with the MDU utility.
