“…The next operation corresponds to subtractive sub group operations, referred to as group partition. Existing studies deal with group communication security requirements that force management to prevent new users from reading communications from the past and departed users from reading future communication [11], [12]. Our group communication security requirements force the management of session-based dynamic group keys.…”

The presence of wireless links makes mobile ad hoc networks more vulnerable than wire-line networks to various forms of attack. Multimedia group communication applications over such Ad hoc networks need a group key to encrypt group call traffic. This security requirement for group communications can be fulfilled by applying dynamic group key management architecture. In this paper, we propose the key agreement architecture that can be realized by encrypting RTP (Real-time Protocol) packets with call-based dynamic group key. We also propose the key control device (KCD) that legally listen to any group call. We solve these contradictory sounding goals: encrypting call traffic and monitoring call traffic. The key agreement part forces every group member to calculate the key tree by means of an iterative Diffie-Hellman group key exchange. In the proposed key management, the transaction manager (TM) is designed to report call information so KCD may compute the same group key for security control. In contrast to the called members, the calling user (that is, TM) generates a random number that is temporarily used as its one time session key doing duty for its original private key. This one time session key will stop the group key being re-used and prevent exploitation of group key weaknesses. Finally, we analyze the computational load (C load ) and message transmission load (MT load ) required for group key computation.

Internet protocol based networking is gaining ground in armed forces, leading to a concept described by the NATO as network centric capabilities (NCC). The goal is to enable state-of-the-art, affordable and powerful electronic information services to the troops. A tighter connection of the forces is expected to further enhance the joined strike capabilities. Providing secure information exchange within groups of armed forces is one aspect of the NCC concept. Such group communication is enabled by the multicast feature of the IP technology. Security requirements are met by using the IP security (IPsec) architecture. IPsec enables secure communication between secure private networks via an unsecured public text network. While secure unicast transmission with IPsec is common, only few achievements have been made to secure multicast transmissions. The protection of multicast data traffic of a group in an automated way is described in this document. We utilize an automatic detection of IPsec devices and an efficient key management protocol to reach our aim.
