In recent years, hacker attacks against industrial control network protocols have occurred continuously, that is, hackers use the loopholes in industrial control network protocols to send wrong information to the inside of the network, disrupt the control of industrial control network equipment, and destroy the communication of industrial control network
The traditional industrial control network protocol analysis and testing method is based on code to build a model. Its shortcomings are: it is not easy to find loopholes in the protocol, and the code uses a static confirmation analysis mechanism, which lacks flexibility and is not easy to analyze

Embodiment 1
[0039] like figure 1 As shown, this embodiment provides a model construction and code generation method oriented to an industrial control network protocol. The detailed implementation steps are as follows:
[0040] S1, obtain and analyze the communication specification of at least one industrial control network protocol, extract the communication process of the protocol, and divide the information in the process into states, trigger events and execution tasks;
[0041] S2, the state is divided into a regular state, an emergency state, an execution state, a loop state or a parallel state according to the specific content; the trigger event is divided into a regular event, an emergency event, an interrupt event or a mandatory event; the event type Fill in the name of the model and the trigger event on the left side of the model, and fill in the state type and state name on the upper side of the model; the execution task is filled in the middle of the model according to the conte...

The invention discloses an industrial control network protocol-oriented model construction and code generation method, which comprises the following steps of: 1, acquiring a communication specification of at least one industrial control network protocol, and planning and analyzing the industrial control network protocol; 2, generating a model according to the communication specification of the industrial control network protocol after planning; 3, detecting whether errors exist in the model or not, and if yes, correcting the model; 4, performing transition simulation on the correct model, and detecting whether the working process of the correct model is consistent with the communication process of the industrial control network protocol; if not, repeating the processes of the step 2 and the step 3; and 5, generating a protocol code according to the model. The industrial control network protocol can be modeled from the perspective of model construction, static and dynamic real-time analysis and real-time improvement are performed on the protocol, and vulnerabilities of the protocol are easy to find; according to the method, codes can be generated through the model, developers do not need to manually write the codes, and work of the developers is relieved.
Description
technical field [0001] The invention relates to the technical field of industrial control networks, in particular to a model construction and code generation method oriented to industrial control network protocols. Background technique [0002] With the full popularization of the Internet, the era of the Internet of Everything is gradually coming. Industrial infrastructure is widely used in aerospace, transportation, resource mining, power grid, communications and other fields. The convenience of the Internet has made it widely used in various fields. On the other hand, it has also brought us more severe challenges. In recent years, there have been more and more industrial information security incidents, which may lead to the failure of industrial infrastructure, economic losses and even casualties to the people, threats to national security or environmental disasters. Strengthening the security defense system of industrial control infrastructure and building a more secure ...
