Modeling And Analyzing Device-sensitive Authentication Process

At the same time as the development of space technology for information physics fusion,it also provides people with a digital environment with increasingly rich services.In this digital environment,the trend of physical fusion of information reflects the real life.Smart devices are the biggest manifestation of this convergence trend.The various business processes that occur based on smart devices have an impact on information space and physical space.The services in the information space affect the contents of the equipment in the physical space,and the behavior of the equipment in the physical space also affects the processes in the information space.Smart devices complicate business processes.This complexity is particularly evident in the context of process integration.Due to the complexity of the process due to the attributes and dependencies of information and physical devices,users and service managers are bothered.On the other hand,cyber criminals also use this to design more complicated processes to commit crimes.Therefore,this paper proposes the concept of device-sensitive business process,and studies the business process in the space of information physics fusion,especially for the study of the performance of business process and business process combination under special circumstances.We incorporate the physical and information entities involved in the business process into the device-sensitive business process model by different physical attributes and information attributes of the entity,dependencies of interrelated dependencies,and changes in attributes and relationships.Petri nets are suitable for modeling discrete systems,so business process modeling is used by many researchers.The equipment-sensitive business process involves many entities,the relationship between the two and the changes in the relationship are complex,and the traditional Petri nets have problems in modeling,which makes the model too large.We use color Petri nets in this paper.Equipment Sensitive Business Process Modeling.On the basis of common business processes,equipment entities are introduced,and the representation method of information entities is changed accordingly,and the relationship between the two is expressed.Based on the proposed color Petri net model,the business process is analyzed,and the performance of the process under extreme conditions(such as mobile phone loss,password forgetting,etc.)is analyzed,and information attributes,physical device attributes,entity binding dependencies are analyzed.Analyze the potential risks of the process in terms of the transfer of attribute relationships and process integration.We translatethe study of business processes into the study of model reachability.Using the modeling and simulation tool CPN Tools,we can study the model through monitors and simulation reports.The color Petri net model presented in this paper integrates the characteristics of common business processes and equipment-sensitive business processes,and expands the equipment for device-sensitive business processes on the basis of common processes.The model can be a good representation of equipment and information,as well as the relationship between equipment and information and changes in relationships.And on the basis of the model,a detailed analysis method is proposed,which can provide the basis for the business process designer afterwards.It has strong theoretical significance and practical value.And this article takes the common equipment-sensitive business process instance authentication business process as an example to explain in detail how to use the proposed modeling method to build the model,use the simulation method to analyze,obtain the potential risk of the process,and illustrate the method Effectiveness.
