摘　　要：传感器网络的固有特点要求密钥建立方案既要达到一定的安全性标准又要高效。基于密钥池的密钥预分配方案虽然比较适合无线传感器网络,但节点的安全链路连通率不高。基于双变量多项式的密钥预分配方案具有高连通率的特点,但安全性存在缺陷。为此,将基于多项式的密钥建立方案与基于密钥池的密钥建立方案相结合,提出一种新的密钥建立方案。分析和实验表明,该方案在安全性、安全链路连通性、可扩展性、有效性等方面和现有一些典型方案相比有较大的提高。The special characteristic of Wireless Sensor Network（WSN） asks the key establishment scheme for WSN to be secure and effective. According to the past research, the key-pool based key establishment scheme is fit for WSN. However, the secure link connectivity of WSN is not so good. The symmetric pair-wise key establishment scheme based on the bivariate polynomial can get a high secure connective link rate, but it does not secure enough. Based on the two schemes, a new key establishment scheme is presented. Analysis and simulation results show that this new pair-wise key establishment scheme makes much more improvement than the classical pair-wise key establishment scheme on the security, the connectivity, the scalability, the effectiveness and so on.
