| Abstract:In order to solve difficulties in key generation and poor anti capture performance of nodes in the field of wireless sensor network security management, a key distribution scheme for WSN based on anti cloning mechanism is proposed. Firstly, based on the hierarchical characteristics of cluster head cluster nodes existing in region shaping, the algorithm adopts anti clone mechanism for node level authentication, and introduces orthogonal mechanism for node key distribution, which realizes the non repudiation feature in the process of key distribution, and reduces the risk of security jitter caused by poor information interaction between cluster head and cluster member nodes. Then, the algorithm adopts asymmetric transmission of ciphertext for key impulse response, and further reduces the probability of key being cracked by reverse distribution, reduces the frequent sending and receiving of signaling in the process of security confirmation, and improves the network transmission performance. The simulation results show that: compared with the polynomial and matrix based key management security scheme in wireless sensor networks (p-mb algorithm) and key pre distribution approach using (Lu) algorithm, which are commonly used in WSN security field Compared with pd-blu algorithm, this algorithm can significantly reduce the probability of node capture, reduce the network signaling transmission, and has strong security distribution and network stability performance, and has high deployment value. |
