With the development of social informatization,all walks of life are on the road to digital transformation,and in this process,as the most important hub between entities and data,digital twin technology has moved from the aerospace field to the industrial control field and is moving to all walks of life.In various industries,the application of digital twin technology in various industries and fields has brought remarkable effects to the industry by leaps and bounds.The research method of the combination of theory and practice of digital twin technology by researchers has laid the foundation for the research of this technology in multiple industries and also left reference examples for other fields.However,while people,enterprises and governments enjoy the efficiency and convenience brought by digitalization and informatization,they also face the security risks brought by them.In this context,the research on network security attack and defense is in the ascendant.Countless new attacks and defense methods are emerging in an endless stream.At the same time,the inability of old technologies and old solutions has become more and more prominent.Four challenges that are difficult to solve in the traditional network system architecture Sexual problems: It is difficult to defend against latent APT attacks,attacks from new attack methods,system stability problems caused by security equipment,and the cost of decision-making and trial-and-error.In view of the challenges faced by the above-mentioned traditional network system architecture,this research firstly investigates the research and application of network information system model and digital twin technology in other industries,as well as related technologies,models and products in the field of network security,and combines the separation of network security business and detection.Based on the idea of the Siamese network,a five-dimensional model of the Siamese network system is proposed,and three working modes of the Siamese network system are proposed for different network security requirements and scenarios.Secondly,this research uses resource and network virtualization technology,SDN technology,and VXLAN technology to design and implement a twin information system construction scheme to solve the key problem of rapid construction of the twin information system experimental environment.Synchronization scheme,at the same time,a multiprotocol compatible pseudo-random number generator is designed and implemented to solve the key problem of state synchronization of the twin information system.Finally,this research verifies the cross-host random number synchronization scheme by embedding the designed pseudo-random number generator into the Linux system kernel and constructing random number synchronization experiments under different protocols.The security-related performance and speed-related performance of the twin information system are verified and analyzed;by simulating different working modes of the twin information system,and constructing attack detection experiments,the network security detection and prediction capabilities of the twin information system under different working modes are verified.By solving the above-mentioned key problems,implementing the proposed twin information system model and cross-host random number synchronization scheme and comprehensively and multi-angle experimental verification of the model and scheme,this research adopts a rigorous approach from theoretical analysis to practical verification.Models and programs are analyzed and demonstrated to provide a strong basis for the effectiveness and feasibility of the models and programs.
