A Novel Key Management Paradigm for Broadcasting to Remote Cooperative Groups

A Mobile Ad Hoc Network(MANET) is a system made up of wireless mobile nodes. These MANET nodes have wireless communication and networking characteristics. MANETs have been proposed to serve as an effective networking system facilitating information exchange between mobile devices even without fixed infrastructures. In MANETs, it is important to support group-oriented applications, such as audio/video conference and one-to-many data dissemination in disaster or battlefield rescue scenarios. In the above group oriented communication scenarios, the common problem is to enable a sender to securely transmit secret messages to a remote cooperative group. A solution to the above problem must meet several constraints. First, the sender must be remote and can be dynamic. Second, the message transmission may cross various networks including open insecure networks before reaching the intended recipients. Third, the data communication from the group members to the sender may be limited. Also, the sender may wish to choose only a subset of the overall group as the intended recipients. Furthermore, it is hard to resort to a fully trusted third party to secure the overall communication. In contrast to the above constraints, mitigating features are that the group members are cooperative and the secret communication among them is local and efficient. This paper exploits these mitigating features to facilitate the remote access control of group-oriented communications without relying on a fully trusted secret key generation center.
