摘要: 现有算法在抗节点捕获攻击方面的性能较差,为此,提出一种基于部署知识的密钥预管理算法,将部署区域划分为若干个互不重叠的三角形网格,并将多密钥空间算法用于相邻的网格。理论分析和仿真实验证明,与现有方案相比,该算法可以使网络在保持较高密钥连通度的同时,较好地抵御节点捕获攻击。

Abstract: Aiming at the problem that many existing schemes have poor resistance to node capture attack. This paper presents a new deployment knowledge-based key pre-distribution algorithm, the deployment area is divided into several non-overlapping triangular grids and multi-key space scheme is applied to each pair of adjacent grid. Theoretical analysis and simulation show that compared with the existing algorithms, network has good resistance to node capture attack while maintaining a higher key connectivity through using deployment knowledge.

Key words: Heterogeneous Wireless Sensor Network(HWSN), key management, deployment knowledge, key connectivity, node capture attack
