摘要: 无线传感器网络预分配密钥管理机制的连通性和抗捕获性较差。为此,提出一种基于网格的密钥机制。任意相邻节点可直接建立密钥对,在被攻击区域中,密钥空间的捕获不会影响其他区域节点的安全性,攻击区域捕获的节点可以方便地被集体撤销,以实现网络及时更新。实验结果表明,该机制具有良好的连通性和抗捕获性。

Abstract: In order to overcome the shortcomings of connectivity and resilience, which are poor in most other secret key predistribution mechanism for Wireless Sensor Network(WSN), this paper proposes a mechanism based on grid. This mechanism can not only guarantee the establishment of secret key pair directly between two adjacent nodes, but also can ensure that the disclose of some secret key space in the area attacked by the enemy cannot affect the security of sensors in other safe area. Besides, the compromised sensors can be removed easily as a whole, facilitating the update of the network. Experimental results show that the mechanism has good connectivity and resilience.
