“…Both keys are used to ensure the forward and backward secrecy based on their lifetime. But in [3], [8] and [9], the authors have shown that the MBRA fails to ensure forward and backward secrecy. Also the MBRA is not scalable for large group as the message complexity is O(n), which means that it increases proportionally with the number of group members, n. Scalable multicast key distribution and group key management protocols specification are amongst few works in secure multicast and broadcast [3] [8].…”

“…In [9], Huang et al introduces an approach that handles backward and forward secrecy, Efficient sub-Linear rekeying Algorithm with Perfect Secrecy (ELAPSE), and a cross-layer approach for an improved version of ELAPSE, namely ELAPSE+. Both ELAPSE and ELAPSE+ are based on Logical Key Hierarchy(LKH), as described in [4] and [9], that works in O(log n) message complexity. The ELAPSE and ELAPSE+ can handle forward and backward secrecy with a set of KEKs and Sub Group Key Encryption Keys (SGKEK), and works in O(log n) like LKH.…”

Many emerging applications that depend on secure group communications demand the privacy of participants and access control at the multicast server. The multicast and broadcast services in IEEE 802.16 are efficient and power saving mechanisms, which no doubt also provide subscribers with strong and powerful security protection from the theft of service by encrypting broadcast connections between subscriber station (SS), relay station (RS), non-transparent relay station (NRS) and Multihop relay base station (MR-BS). However, the existing multicast and broadcast rekeying algorithm (MBRA) not only facing forward secrecy, backward secrecy and scalability problems for IEEE 802.16e but also for multihop relay based networks both in centralized as well as distributed zone. Although many researches try to give solutions for the above problems, all of them focus mainly on IEEE 802.16e networks and none of paper is published on distributed relay-based Wimax networks. This paper illustrates the main security problem of MBRA in general which is scalability, backward and forward secrecy and proposes a new Secure and efficient distributed Relaybased Rekeying Algorithm (SEDRRA) scheme for nontransparent Multihop IEEE 802.16 networks. The proposed scheme uses non-transparent decode and forward relays. Both analysis and performance evaluation show that our scheme can significantly reduce the complexity and solve all of the above problems in an efficient way.

In mobile multihop relay (MMR) networks, Relay multicast rekeying algorithm (RMRA) is meant to ensure secure multicast communication and selective updating of keys in MMR networks. However, in RMRA, the rekeying is carried out after a specific interval of time, which cannot ensure the security for multicast communication on joining the member. Secondly, the rekeying scheme generates a huge communication overhead on the serving multihop relay base station (MR-BS) on frequent joining of members. Lastly, there is nothing about when a member left the group communication. Thus, the rekeying scheme of RMRA fails to provide forward and backward secrecy and also is not scalable. To solve this problem, an improved rekeying scheme based on broadcasting a new seed value on joining and leaving of a member for updating the ongoing key management is proposed. The proposed scheme solves the issue of forward and backward secrecy and the scalability in a very simplified way. The forward and backward secrecy of the proposed scheme has been extensively validated by formal method using rank theorem. Furthermore, mathematical derivation showed that the proposed scheme out-performed the RMRA in terms of communication cost and complexity.
