An identity-based wireless sensor network key management method

Abstract

The invention discloses an identity-based wireless sensor network key management method, which specifically includes the following steps: (1) network parameter initialization stage; (2) sensor node registration and clustering stage; (3) sensor node key negotiation stage within the cluster . The invention adopts Bloom Filter technology to realize the legality verification of the public key, avoids the complicated authentication process of the certification center, and saves a large amount of storage space; the invention adopts an identity-based key management method to improve the security of the key management process sex.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an identity-based wireless sensor network key management method. Background technique [0002] The rapid development of the three major technologies of computing, communication and sensors has given birth to wireless sensor networks. At present, wireless sensor networks have been more and more widely used in many fields such as military defense, environmental science, medical health, space exploration, construction and remote control in dangerous fields. [0003] Since the architecture of the wireless sensor network is open, some of its own characteristics determine that the security of the network is poor, and the adversary can easily eavesdrop, intercept and forge the transmitted information, so the security becomes the most important issue of the wireless sensor network. One of the key issues that need to be solved urgently. Constructing a safe and effective key man...
