A Sink Node Trusted Access Authentication Protocol for Mobile Wireless Sensor Network Using Block Cipher Algorithm Based on IoT

摘要

Aiming at the problem that mobile nodes in Wireless Sensor Network (WSN) lack credibility verification, a Sink node trusted access authentication protocol using packet cipher algorithm for mobile WSN is proposed based on the Internet of Things (IoT) environment. Firstly, the mobile Sink node is utilized to authenticate the sensor node and verify the platform's credibility of the mobile node. Secondly, pre-stored pseudonyms and corresponding public and private keys of mobile nodes are utilized to realize the anonymity of mobile nodes, and the security proof is given under CK (Canetti-Krawczyk) model. Finally, the block cipher algorithm is introduced, and the advantages of the two algorithms are fused. The correctness and security of the proposed protocol have been proved by the verification experiments. In addition, compared with other authentication protocols, the proposed protocol has lower communication overhead.
