仿生视角的数字孪生系统信息安全框架及技术

为了推动工业信息安全防御模式从静态的被动防御向主动防御转变，缓解安全专家严重不足与陡增的信息安全需求之间的矛盾，从仿生视角搭建数字孪生系统的信息安全主动防御体系框架，以数字孪生安全大脑为核心，提出以主动防御为目的的5类关键技术：基于云边协同的安全数据交互及协同防御技术、仿生的平行数字孪生系统主动防御技术、仿生的平行数字孪生系统安全态势感知技术、基于免疫系统的数字孪生系统主动防控技术、基于AI的数字孪生系统的反攻击智能识别技术. 给出数字孪生车间信息安全建设的应用案例，验证了数字孪生信息安全在智能制造中的适应性.

Framework and key technologies of digital twin system cyber security under perspective of bionics

In order to promote the transformation of industrial cyber security defense mode from static passive defense to active defense, and alleviate the contradiction between the serious shortage of security experts and the sharp increase of cyber security demands, a cyber security active defense system framework of digital twin system was built from the perspective of bionics, and then five kinds of key technologies focusing on active defense were proposed based on the digital twin security brain (DTSB), including security data interaction and systems collaborative defense based on cloud-edge collaboration, cyber security active defense model of parallel digital twin system, situation awareness of parallel digital twin systems based on digital twin security brain, active defense and control technical framework for digital twin system based on immune system, and anti-attack intelligent recognition of digital twin system based on artificial intelligence. A case study of a digital twin workshop was given to demonstrate the successful application of digital twin cyber security in smart manufacturing.
