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.
