“…Due to the reason that the movement between two subgroups in the centralized protocols give rise to two subgroup re-keying and the global key update, which is much bigger than our protocol in PKI. In such regular case, our protocol just gets 25% and 55% of the real re-key messages and the re-key events compared to centralized protocols without PKI in average respectively [8,15,16] .…”

“…Similar to a join event, the re-keying process only happens within the subgroup by multicasting the new K S,i to the remaining group members encrypted by members' individual keys. While in centralized key management schemes without PKI [8,15,16] , the group manager still needs to update the global group key and subgroup key database and Let P denotes the data packets; ) (P K + means using K to encrypt P ; and ) (P K − means using K to decrypt P .…”

Abstract. This paper describes a secure multicast infrastructure for large-scale group communications in Mobile Internet and proposes a key management protocol based on the infrastructure. The multicast communication domain is logically divided into several administrative areas with a key server associated with each area. All the key servers participate in a Public Key Infrastructure (PKI) as trusted entities known by the subgroup members. Therefore, it's efficient to minimize the re-key overhead implemented in the mobile host tier. The simulation results show that the proposed protocol has better performance compared to the centralized protocols without PKI support. The numbers of the real re-key messages and the re-key events are reduced to approximately 30% and 65%, respectively.

“…Because the PK(SGKS i ) of SGKS i is not altering as the change of K S,i , and the K S,i is only generated by SGKS i , it's apparent that other subgroups needn't to carry out the re-key operations. All the rekey operations are accomplished by the SGKS within the subgroup, and the whole overhead is only concerned within the changing subgroup, which is apparently reduced compared to the centralized protocols without PKI [8,15,16] .…”

“…Various extensions were proposed to deal with reliability [15], node dependent group dynamic [16], and time variant group dynamic [4,11]. Extensions to wireless networks were first discussed in [17] and several secure multicast protocols were proposed [18][19][20]. These protocols addressed both issues related to mobility and unreliability.…”

In this paper we address the problem of secure multicast of data streams over a multihop wireless ad hoc network. We propose a dynamic multicast group management protocol that aims at solving problems that are specific to ad hoc networks such as mobility, unreliable links, and cost of multihop communication.The main idea is to have group members actively participate to the security of the multicast group, therefore reducing the communication and computation load on the source. Since the group security is distributed among the group members, we propose a service right certificate, to verify that a node is authorized to join the group, and also a corresponding revocation mechanism. We simulated our protocol within the ns-2 environment under various mobility, group size, and group dynamic scenarios. Our simulation results indicate that the communication cost and join delay of the protocol scale well when the group dynamic and nodes mobility increase. We have implemented the basic protocol in our ad hoc network testbed. We also proposed an extension to the basic secure multicast tree using multi-link capability combined with a k-out-of-N coding approach.
