针对无线传感器网络(WSN)的安全问题，结合椭圆曲线密码体制，提出一种基于信誉模型的 WSN 密钥管理方案。依据Beta分布建立节点信誉模型，采用分布式技术使方案支持节点的移动和密钥的动态管理，以避免分组密钥管理中的单点失效现象。分析结果表明，与E-G和IBC方案相比，该方案不仅能抵御外部节点的攻击，而且能防止内部节点的恶意行为。在保证网络安全的同时，还能提高网络抗毁性和节点连接概率，降低存储与通信开销。

Focusing on the study of the security in Wireless Sensor Network(WSN), combined Elliptic Curve Cryptosystem(ECC), this paper presents a key management scheme based on reputation model. It provides reputation model based on Beta distribution. A single point of collapse problem in group key-management is avoided due to distributed key establishment, to update among the nodes and support node mobility and dynamic key management. Analysis results show that, compared with E-G and IBC scheme, this scheme not only can resist the attacks from outside nodes, but also can prevent attacks or malicious behaviors from internal nodes. The performances of WSN security, invulnerability, connection probability of nodes, less storage and communication overhead, can be substantially improved by using the scheme.
