This should be taken up with the HSM provider as it is not an STSA issue, but a commercial one.

Please contact the HSM provider since this depends on the level of HSM that you have.

Both the manufacturing and vending HSM’s must be able to implement the different base dates, as well as the new decoder key generation algorithm (DKGA04) required for the TID rollover. The existing SGC’s will be retained in the modules, however, when doing the TID rollover, the key revision number (KRN) will be incremented to the next available number when generating the meter keys.
