Abstract

The invention discloses a heterogeneous wireless sensor network predistribution key management method, relates to the network predistribution key management method and aims at solving the problem that according to an E-G scheme, the network security is relatively low and a possibility that key repetition occurs is relatively high, according to a q-composite scheme, the destroy-resistance is relatively poor as the number of damaged nodes is increased, according to a single key space scheme, cost and occupation of resources of nodes are relatively high, and according to a traditional isomorphic WSN key management scheme, a heterogeneous feature of the nodes is not taken into consideration and certain limitations exist. A process comprises the steps of S1, establishing an HWSN cluster model; S2, establishing an SAAP scheme under the HWSN cluster model established in the S1; and S3, adding a new node in the network after the SAAP scheme is established in the S2. The method is applied to the field of network predistribution key management.

Description

technical field

[0001] The invention relates to a network pre-distributed key management method. Background technique

[0002] With the wide application of wireless sensor networks, its security issues also arise at the historic moment. The security mechanism of wireless sensor network includes secure routing, secure positioning, topology management, data fusion and so on. Key management is a fundamental issue in the security of wireless sensor networks. Since WSN security attracted people's attention, isomorphic WSN key management has become a research hotspot for scholars; the basic random key pre-distribution scheme, referred to as the E-G scheme, is simple to implement, has low computational complexity and low storage requirements, but due to the The scheme is based on probability, so the security of the network is low, and at the same time, the possibility of key repetition in this scheme is relatively high. The q-composite scheme proposed by Chan et al. is an improv...
