基于矩阵格的传感器网络密钥预配置方案

Matrix grid-based key pre-distribution in sensor networks

为了提高传感器网络的安全性能,在密钥管理中提出了矩阵池、矩阵格的概念,将密钥的预配置建立在多个密钥矩阵之上,并将加密传输机制应用到密钥的传输过程中,以提高密钥传输过程中的安全性。通过借鉴Blom的预配置方案,设计出一个应用于传感器网络的高效密钥对预配置方案。

To solve the security problem of wireless sensor networks, the concept of matrix pool and matrix grid were put forward, upon which our key pre-distribution scheme was built. And in the matrix grid based scheme, encryption was introduced into the process of key transfer. Using Blom＇s key pre-distribution for reference, an efficient key pre-distribution scheme was presented for sensor networks.
