Ship identity authentication security model based on Blockchain

The accuracy of ship information directly determines the efficiency of ship management and the safety of navigation, which are important in shipping management for ensuring the truthfulness, reliability and credibility of ship information. Therefore, to meet the needs of shipowners, shipping authorities and third-party users, this paper studies the ship information authentication system based on the blockchain smart contracts and security mechanisms and proposes a framework for storing and sharing ship information based on blockchain in multichannel mode. In the framework, token-based authentication, attribute-based fine-grained permission control, and a combined security model based on the transmission encryption of double asymmetric certificates are developed to authentication the identity of each agent and control the access rights of ship information in the blockchain data storage mode. We use the automated verification tool Automated Validation of Internet Security Protocols and Applications to verify the security of the modeladditionally, the performance of the system is tested and analyzed, and the optimal parameter range is obtained. The proposed system can solve the long-standing trust and security problems of ship communication while guaranteeing performance.
