An Authentication Key Agreement Scheme for Heterogeneous Sensor Network Based on Improved Counting Bloom Filter

In terms of the problems of security, scalability and communication cost existing in the scheme, which is proposed by Qin et al., of identity-based key management using bloom filter (IBKM), this paper designs an authentication key agreement scheme for heterogeneous sensor network based on improved counting bloom filter. This scheme analyzes the problem of authentication key agreement in heterogeneous sensor networks from the viewpoint of Set theory and improves the algorithm of counting bloom filter to be adapted to the authentication key agreement of heterogeneous sensor networks. The experimental results show that the proposed scheme can resist brute force attack during a node capture and has better network scalability and lower communication cost compared with the IBKM scheme.
