SUMMARYKey management becomes more difficult in multiprivileged group communications due to the dynamic membership and the complex relations between users and resources. Because centralized key management schemes have the drawbacks of the single point of failure, and performance bottleneck and distributed key management schemes are not scalable and lack of central control, decentralized key management schemes are proposed as a tradeoff between them. In this paper, we propose a decentralized group key management scheme using multilinear forms for dynamic multiprivileged groups. Once users join/leave the group and change their privileges, the related session keys should be updated. The rekeying in the joining operation is relatively simple because the keys are deduced from the previous keys based on a one-way function. When rekeying for one leaving/switching operation, a uniform rekeying material is negotiated between the related service groups (SGs) by using multilinear forms. Compared with other schemes in which several rounds of negotiations are executed for rekeying in each joining/leaving/switching operation, only one round of negotiation is required in each leaving/switching operation of our decentralized group key management scheme. At last, the affected session keys can be deduced by the related SGs. Our proposed scheme also supports the dynamic formation and decomposition of SGs, which provides good scalability. Security analysis is provided to show that the proposed scheme is secure. The performance analysis and the simulation results show that the proposed scheme reduces the communication cost greatly.

“…组播是一种可以把同一份数据发送给多个接收者的有效通信方式。与单播通信方式相比，组播可以有效地减少发送者的资源开销以及节省网络带宽等优点，因而很受多媒体商业组织、软件生产商、教育机构等行业的欢迎。可以利用组播方便地进行内容分发，比如进行付费电视的内容的播送、远程视频点播、远程会议等。组播要在商业上成功应用必须要解决组播的安全问题。由于信息的机密性、完整性、不可认证性等基本都是用密码来实现的，而密码体制的安全主要依赖于密钥的安全管理，因而在网络安全中密钥管理的意义就显而易见。组播相比于单播, 其密钥管理面临着更多新的难题和挑战，如前向保密 (Forward confidentiality) 、后向保密 (Backward confidentiality) 、合谋攻击及组播成员的动态变化等。为了解决这些问题, 近年来, 提出了一些组播组密钥管理方案,如 GKMP(Group Key Management Protocol) [1,2] 集中控制的组播密钥管理协议、基于树的 LKH(Logical Key Hierarchy)协议 [3,4,5,6] 等。在 GKMP 和 LKH 等组播密钥管协议和方案中，在密钥服务器遭受物理攻击后，容易泄漏密钥等重要数据，而且 GKMP 和 LKH 等组播密钥管理方案其密钥更新的代价比较高。 [7,8] …”

Multicast is an efficient delivery which an identical data is sent to many group members from a multicast source or many multicast sources. However, there is a growing need to conquer the multicast security problem limiting its successful and extensive application. In this work, an efficient and trusted group key management protocol (EGKMP) is proposed, compared to previous tree-based key management protocol LKH and Group Key Management Protocol GKMP, EGKMP protocol can efficiently reduce the amount of key update messages, due to the operation of group member to join and leave the multicast group, in fact, the protocol eliminates the rekeying process. EGKMP protocol also utilizes TPM to credibly produce, store and distribute keys, the trustworthiness of its key management is superior to tree-based protocol LKH and GKMP. Security analysis, performance analysis shows that EGKMP agreement is the desired efficiency and trustworthiness.

“…The Wireless Mesh Network (WMN) has been envisioned as the economically viable networking paradigm for scalable QoS-aware delivery of heterogeneous traffic over broadband and large-scale wireless commodity networks (Wang et al, 2005;Martinez and Bafalluy, 2010). WMNs consist of mesh routers and mesh clients, where mesh routers, as opposed to nodes in a mobile/static ad hoc network (MANET) (Jeong et al, 2007;Yang and Wang, 2009;Rabara and Vijayalekshmi, 2011;Palanisamy and Annadurai, 2011;Cao et al, 2009;Mohamed and Alnuweiri, 2009) have minimal mobility and form the backbone of WMNs. They also provide network access for both mesh and conventional clients (Wang et al, 2005).…”

Multicast is a key networking service, enabling one-shot delivery of information from a source to multiple destinations and is considered underlying for collaborating multimedia applications such as video conferencing, distance learning and other forms of content distributing over Multi-Channel Multi-Radio Wireless Mesh Networks (MCMR WMNs). Multicast protocol as designed in these networks, however, is tightly coupled with the specifics of the nodes' channel-radio associations to realise minimum interference communication. The mainstream of research in WMN multicasting is oriented towards heuristic or meta-heuristic strategies which basically take on a sequential approach to solve the channel assignment and the multicast routing as two disjoint sub-problems. The resulting network configurations would be sub-optimal in this case. It is given that the cross-interaction between the two sub-problems is an effect of the problem's specifications. In this paper, first, we propose a cross-layer mathematical formulation of joint channel assignment and multicast tree construction in MCMR WMNs, which, opposed to the existing schemes guarantees optimal solution. The simulation results demonstrate that our cross-layer design outperforms the Level Channel Assignment (LCA), Multi-Channel Multicast (MCM), the Genetic Algorithm (GA), Simulated Annealing (SA) and the Tabu Search (TS)-based methods proposed by Zeng et al. (2010) and Cheng et al. (2011) respectively, in terms of inter-channel interference. Second, since joint optimisation modelling has been relatively demanding in terms of complexity, we relax the optimality requirement and alternatively explore the option of a layered formulation in which to ensure an optimal solution for each sub-problem. Our alternative design is proved superior to the prior art in terms of interference minimisation too. We conduct an extensive series of simulations to analyse the optimality and complexity of our two design strategies. The overall result of the interference, is our optimality measurement. Also, complexity is evaluated in terms of the memory consumption as well as the required time to solve the multicast problem.
