Authors - Thaw Thaw May Oo, Khaing Khaing Wai Abstract - Modern maritime industry depends largely on digital communications and access control systems for their operation and security maintenance. On the other hand, digital communication and access control systems make maritime industry more vulnerable to cybersecurity attacks, such as unauthorized access, data leaks, and insiders' malicious actions. Centralized security measures become inefficient against modern and advanced cyber threats. In that regard, this paper presents a Smart Digital Lock System using Zero Trust Architecture and AES Encryption. The suggested approach assumes the implementation of zero trust policy in terms of continuous user identity validation requiring tight access control, including strict user authentication and monitoring. Multifactor authentication and real-time monitoring are the key characteristics of the suggested system, especially considering such potential high-risk zones as ships and ports. Communication of authorized parties will be performed using the AES encryption to protect the information's privacy and integrity. As a result, the presented system will be assessed from three perspectives: authentication accuracy, data protection effectiveness, and response latency.
