Erase Previous Keyset on OTAR Changeover |
(Secure KMF Profile, ASTRO OTAR Information) |
Enables the erasing of ALL encryption keys in the previously active
Keyset after an ASTRO OTAR (Over-The-Air-Rekeying) keyset change has occurred.
An OTAR keyset change is initiated from the Key Management Facility (KMF),
or by the radio-user
with a CPS-programmable 
Rekey
menu selection. This feature applies to ASTRO OTAR operation for the current
Secure KMF Profile.
|
When this Erase Previous Keyset on OTAR Changeover field is enabled and when the Erase Previous On User Change is enabled, it is possible for the radio-user to erase both keysets and be momentarily without any secure encryption keys. EXAMPLE: The radio is currently operating on Keyset 1 when an OTAR Keyset Change occurs; it changes the radio to Keyset 2 and erases the radio's previous Keyset 1. Then if the radio-user manually changes back to Keyset 1 that has been erased, and the Erase Previous on User Change feature erases the previous Keyset 2, then the radio would remain keyless until the radio-user manually loads new keys, or requests a manual OTAR Rekey. |
When the Secure Operation field is set to "Hardware", and
when the OTAR Enable field is enabled, and
when the ASTRO OTAR Enable field is enabled, and
when the radio is model / option capable.
