中文摘要：

在无线传感器网络体系结构中,分簇路由机制是研究的关键问题.针对分簇路由过程难以抵御恶意节点攻击问题,提出了一种基于椭圆曲线密码机制的安全分簇算法.以离散对数困难问题保证算法的安全性,从而有效抵御恶意节点攻击,并且详细给出了安全分簇算法实现过程.在分簇安全的前提下,使用EECF概率打分思想实现簇中所有节点地位平等,能量消耗均摊,进而有效地延长网络生存周期,适应于无线传感器网络的实际情况.最后对方案的安全性进行了证明分析.

英文摘要：

Clustering routing mechanism is a critical issue in wireless sensor network（WSN）architecture.Aiming at the problem of resisting attacks of malicious node in clustering process,a kind of secure clustering algorithm based on elliptic curve cryptosystems（ECC）is presented.Discrete logarithm problems ensure the security of the algorithm and effectively complete the mission against malicious nodes attacks,and the implementation process of the secure clustering algorithm is given in detail.On the premise of clustering security,all nodes have equal status and energy consumption uniform is implemented by using EECF probability scoring ideas,thus to effectively prolong the network lifetime and to be suitable for the actual situation of wireless sensor network.The security of the scheme is discussed in the last part.
