DFSMSdss supports encryption for DUMPs. I believe you need the software
encryption facility on your system and then a license to allow DSS to use
it. Usage is explained in the z/OS V1R11.0 DFSMSdss Storage Administration
guide.
DFSMSdss can use the following types of host-based encryption to secure
your data:
* Triple-length Data Encryption Standard (TDES) clear keys
* Secure TDES keys
* 128-bit Advanced Encryption Standard (AES) clear keys.
If extra CPU cycles are available then host based encryption can be a good
solution. If not, hardware encrypting tape drives are a good option if that
is a concern. The hardware encrypting tape drives actually encrypt in
real-time as the data is written to the tape.
Just wanted to let you know the options out there in regards to DFSMSdss.
