| 摘 要： | 由于无线传感器网络在能量消耗、内存开销和计算能力等方面的局限性，传统的网络密钥管理方法已不适用。为此提出了一种适用于无线传感器网络的密钥预分配方法——基于（t，n）-门限方案，给出了密钥分配方法，并从方案的连通性、安全性等方面进行了有效的分析，结果表明该算法在这些方面有一定的优势。

| Abstract: | It is a great challenge to find out a suitable key establishment scheme for wireless sensor networks due to limitations of power, storage resources and computation capability. Many schemes based on random predistribution technique and public key cryptography are investigated. A new scheme for key predistribution and exchange in wireless sensor networks is proposed in this paper. A novel key assignment scheme based on the basic （ t, n） - threshold scheme is described. The efficiency and security of our scheme by comparing with other normal key assignment schemes are also discussed. |
