針對無線傳感器網絡節點能量、計算和帶寬有限的特點，提出一種適用于無線傳感器
網絡的基于分簇的安全組播路由協議（CSMR）。該協議采用了HiM-TORA 的樹形組播尋路機制，并引入了TESLA 密鑰鏈與時間同步等安全機制，能夠自動且安全地構建覆蓋所有組播組成員的組播樹，且在路由建立的階段就能對成員的身份和相關的信息進行認證，有效的防止了對組播路由的各種攻擊。同時分析了該協議的安全性與有效性。

Clusering-Based Security Multicast routing Protocol for wireless sensor network Cheng Yali, He Bo (Ocean University of China, Qingdao, China 266071) Abstract: The wireless sensor network is characteristic of limited node energy, computation and memory, so many traditional security methods, such as the public key algorithm and the digital signatures, are hardly used on it. To solve such problems, we proposed a novel secureity multicast routing protocol for clustering-based wireless sensor network(CSMR). In CSMR, we use HiM-TORA to construct multicast routing tree, and include TESLA key chain technology to make it secure. In the process of constructing the routing, it can authenticate the group member’s identifier and correlation information.The scheme is proved valid through the theoretic analysis.
