Abstract

The invention being described is a new method to rekey a radio. This method is different than cur- rent OIAR implementation since the key(s) are never sent over the air. The subscribers will be given a longer "superkey" which will be used to store shorter traffic and key encryption keys. For example, a 128 key superkey will be stored in the subscriber and individual keys will be selected from the superkey to be used by the subscriber. The KMC will send start and end pointers over the air during rekeying, giving the new key location and the key location to be replaced.
