论文摘要
当前，数字双胞胎的大多数研究都集中在模拟和优化上。数字双胞胎对于关键系统特别有用。但是，数字双胞胎也可以用于安全和网络安全。本文的想法是由网络物理系统（CPSS）的网络安全局限性的促进。我们引入了一种有效的同步方法，以维持虚拟环境和物理环境之间的状态。在这种情况下，我们可以通过在虚拟域中进行安全分析来收到及时的反馈。因此，有助于提高CPS的网络安全性，我们提出了一个基于数字双胞胎的框架。基于该方法，CPS的安全性可以受到数字双胞胎系统的保护。此外，提议的体系结构还进行了优化，以满足安全要求并保持CPSS的网络负担减少
Currently, most of the research in digital twins focuses on simulation and optimization. Digital twins are especially useful for critical systems. However, digital twins can also be used for safety and cyber security. The idea of this paper is motivated by the limitations of cyber security in Cyber-Physical Systems (CPSs). We introduce an efficient synchronization approach to maintain the state between the virtual environment and the physical environment. In this case, we can receive prompt feedback by conducting security analysis in the virtual domain. Thus, helping to enhance the cyber security of CPSs, we propose a digital twin-based framework. Based on the approach, the security of the CPSs can be protected by the digital twin system. Moreover, the proposed architecture has also been optimized to meet the security requirements and maintain less network burden for CPSs
