船舶数字孪生目前存在的物联网安全威胁综述OA

With the acceleration of digital transformation in the shipbuilding industry,Digital Twin technology significantly improves the efficiency of ship design,manufacturing,and operation and maintenance through the real-time interaction between physical ships and digital models.However,ship Digital Twin systems under the Internet of Things(IoT)environment face multiple security threats.This paper systematically analyzes the core architecture and application scenarios of ship Digital Twin technology and focuses on the IoT security challenges it faces.The study finds that expanded attack surfaces,data leakage and tampering,identity authentication loopholes,network attacks(such as Man-in-the-Middle attacks and DDoS attacks),and software attacks are the main threats.These risks not only threaten the integrity of sensitive data but also affect the navigation safety of ships through remote control.The study further points out that existing security protection measures have deficiencies in standardization,dynamic authentication mechanisms,and cross-layer collaborative defense.By reviewing literature and analyzing cases,this paper provides theoretical support for the security protection of ship Digital Twin technology and calls on the industry to pay attention to security governance throughout the full life cycle.
