Problems solved by technology

[0003] In the communication protocols of traditional computing platform systems, people generally use natural language to describe it. Although natural language has the advantages of being easy to understand and convenient, it also has many fatal shortcomings. For example, natural language is not accurate enough. Strictness and ambiguity, etc., will cause different people to have completely different understandings of the protocol description, resulting in wrong communication protocols
In order to achieve the purpose of safe and reliable data transmission, the method of verifying the communication protocol can detect errors and defects to the greatest extent. Communication protocol verification includes informal verification and formal verification, and non-formal verification often lacks mathematical rigor Sexuality and scientificity, it is difficult to guarantee the quality of verification results

Abstract

The invention discloses a communication protocol credibility verification device which comprises the components of a formalized language description module which is used for describing a requirement specification that satisfies a safety transmission index through a formalized language and obtaining a requirement specification that is described by the formalized language; a formal verification module, used for verifying the requirement specification described by the formal language through a formal verification tool to obtain a verification data set; and a detection module used for performing standard detection according to the verification data set. By means of the device, the formalized verification tool can be used for verifying the requirement specification so as to guarantee the safetyand reliability of data communication of the computing platform system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication protocol authenticity verification device. Background technique [0002] Computing platform systems play an important role in many fields such as industry and life today. In addition to the traditional personal computer field, they also occupy a very important position in emerging technology fields such as smart factories and smart driving. It is worth noting that today's computing platform is no longer a simple operation of a single node. Today's computing nodes are networked and systematic. Computing platform systems form a powerful platform system through data communication, and computing platform systems are reliable. The data communication is the basis to ensure the safe operation of the entire software, and the communication between computing platform systems is restricted by the communication protocol of the platform. [0003] In the communication p...
