Changing cryptographic keys dynamically

z/OS Communications Server: SNA Network Implementation Guide
SC27-3672-01

You can change LU and CP/SSCP resource keys for a session while VTAM® is running. This enables you to avoid synchronization problems when changing keys, and helps reduce down time when changing static definitions.

By coding the appropriate operands and issuing the appropriate commands, you can:
  • Use alternate LU key-encrypting keys while you change the LU master key in the CKDS at the control point (CP/SSCP).
  • Use alternate CP/SSCP import and export key-encrypting keys (KEKs) while you change the corresponding import/export values in the CKDS at each control point.
