Key Management Using Dynamic Multicast Functionality of OMCT

There are many applications like military or public emergency have main concern with secure communication. All this applications use ad hoc environments, so secure key management and message distribution is necessary. The best solution to provide the reliable security to these services is the stipulation of a key management protocol. This paper shows the specific challenges towards key management protocols and different approaches for key management. It also shows the multicast communication with OMCT and its limitations. A new approach, called combination of OMCT with DSDV, can be good. It is not required geographical location information for true connection. It provide high packet ratio with less energy consumption and delay.
