密钥预分配方案在安全体系结构占据着极其重要的位置。基于网络区域信息,提出了一种基于分簇结构的无线传感器网络密钥预分配方案,该方案可以确保任意两个相邻节点之间都能够建立一个唯一的对密钥。理论分析表明,该方案在安全性、扩展性等方面都具有明显的优势。 The key pre-distribution scheme occupies a very important place in the security architecture. Based on the network area information, a key pre-distribution scheme for wireless sensor networks based on clustering is proposed. This scheme can ensure that any two adjacent nodes can establish a unique key pair. Theoretical analysis shows that the program has obvious advantages in terms of security and expansibility.
