发明名称 Method and apparatus for over-the-air programming of communication devices
摘要 In a communication system (300), a controller interface (302) provides for monitoring of channel activity in order to determine communication devices (400) which are communicating using old encryption information. Upon a key management controller (306) determining that one or more communication devices are using an old encryption scheme, the key management controller (306) establishes communications with the communication device(s) (400) and provides them with the new encryption information.
