Problems solved by technology

[0008] The disadvantage of the protocol correctness verification method based on a single formal model in the prior art is that each single formal model has its pertinence and focus, but none of them are comprehensive, and cannot guarantee the correctness in the initial stage of protocol design. It can realize the complete correctness verification of the protocol
Since the design, formal description and verification of the protocol are all carried out by humans, there are inevitably human errors in the protocol verified by a single formal model
The existence of these errors will lead to implicit errors in the formal description of the protocol, which is not complete enough, which in turn will lead to implicit errors in the generated protocol test sequence and the final protocol test results, which are not complete

Embodiment Construction

[0042] The invention provides a protocol correctness verification and testing method based on model conversion. The core of the present invention is: because the probability of the same error occurring in the protocols described by different formalized models is very small, so various formalized models for the same communication protocol are converted into the same formalized model, and then After the converted models are compared with each other, the logical errors in the formal description of the protocol can be located and corrected. In order to realize the correctness verification of the agreement.

[0043] Describe the method of the present invention in detail below in conjunction with accompanying drawing, the specific processing flowchart of the method of the present invention is as follows figure 1 shown, including the following steps:

[0044] Step 1-1. Formally describe the communication protocol to be verified and tested by using at least two typical formalized mo...

Abstract

This invention relates to a kind of model conversion based protocol correctness verification and testing method. The method concludes: at least two kinds of formalized models are used to formalize descript protocols; the said two kinds of formalized models are converted respectively to the same kind of formalized models; the verified protocol formalized model is acquired through comparing the differences between the said same kind of formalized models. Based on the said verified protocol formalized model, the correctness verification and testing of protocol is carried out. This invention can also be used to develop testing system tools that aim at concrete protocol.

Description

technical field [0001] The invention relates to the protocol engineering technology in the modern communication field, in particular to a protocol correctness verification and testing method based on model conversion. Background technique [0002] With the improvement of network service requirements, the complexity of network systems requires that high-quality communication protocols can no longer be designed by engineering intuition. Protocol Engineering (Protocol Engineering) technology uses formal methods to describe protocol design and maintenance. The various activities in the protocol make the whole process of protocol development integrated, systematized and formalized, so as to ensure the integrity, correctness, security and portability of the protocol. [0003] With the improvement of protocol formal description technology, the development method of network communication protocol will gradually transition from informal description and manual method to software engin...
