In this paper, a wireless sensor network security key distribution method based on DV-Hop algorithm is proposed. The improved DV-Hop algorithm is used to locate the network security key distribution point, and the distributable point is separated according to the positioning result. According to the separation result, a key management tree is introduced to perform centralized classification management of allocable points, and the key management tree is used to complete the wireless sensor network device authentication, key distribution and update, and to realize the research of the wireless sensor network security key distribution method. Experimental results show that the method uses low energy for key establishment and update, the minimum update energy consumption is only 25 μJ, and it has strong anti-attack performance and high overall security.
