Key management in a two-way radio system can be a challenging and time consuming task, especially in large systems. Over the Air Key Management (OTAK) is an effective method of maintaining and updating encryption keys in a two-way radio system. As with any task, there is a continued desire to improve the efficiency of the key management process. This is especially true when there is a large number of radios or end devices that are key managed in a two-way radio system. It is desirable for key management to be as unobtrusive as possible to other services offered in a two-way radio system. The more efficient the key management service is, the better the performance of the two-way radio system for key management and other services.
