智能船舶信息交互对航行安全至关重要。为抵御海上黑客攻击，提高智能船舶信息交互的安全性和可靠性，提出一种基于区块链的智能船舶信息交互技术架构并开发试验系统。首先，分析智能船舶信息交互的现状及区块链技术基本原理，阐明区块链在保护智能船舶信息交互安全方面的优势；其次，提出上链信息种类及信息在区块链内的交互流程，选用联盟链开发智能船舶信息交互试验系统；最后，结合海上实际应用场景进行模拟，验证该系统的可行性。研究发现，区块链能有效解决智能船舶信息交互中的安全问题，保护数据的不可篡改性、隐私性和实体身份的真实性。本文为智能船舶信息交互提供了一种新的解决方案，也为海上交通管理和智能船舶技术的发展提供了有价值的参考。
Intelligent ship information interaction is very important to navigation safety. In order to resist hacker attacks from sea and improve the security and reliability of intelligent ship information interaction, this paper proposes a technical framework of intelligent ship information interaction based on blockchain and develops a test system. First of all, by analyzing the current situation of intelligent ship information interation and the blockchain technology, this paper exponds the advantages of blockchain in protecting intelligent ship information interaction safety. Secondly, the types of data that the intelligent ship should transmit within the blockchain are put forwards, and how these data are transmitted in the blockchain are explained, then an alliance chain is chosen to develop the intelligent ship information interaction test system. Finally, the feasibility of this system is verified by simulating an actual offshore application scenario. It is found that the blockchain can effectively solve the security problem of the intelligent ship information interaction, and protect the data's untamability, privacy and entity's authenticity. This paper provides a new solution to intelligent ship information interaction, and also provides valuable reference for the development of marine traffic management and intelligent ship technology.
