Abstract

In an ASTRO 25 Over The Air Rekeying (OTAR) system, the Key Management Facility (KMF) distributes keys to all secure components in the system. Ideally, only the KMF should be able to configure keys in any unit. But, that is not the case. A user can change the keys via the Key Variable Loader (KVL) or also erase the keys in the unit without KMF's knowledge. This would make the unit and KMF out of sync with each other.
