Embodiment Construction

[0045] In order to solve the technical limitations of Go language formal semantics in terms of comprehensiveness and verification, and for program vulnerability analysis in the prior art, the present invention proposes a program vulnerability analysis method based on rewriting logic executable formal semantics, Executable formal semantics are implemented in the K framework. First, based on the K framework, the language rules can be specified modularly and accurately represent the real concurrent programming language, which is especially suitable for the analysis of the concurrent language Go language. Second, the semantics in K have strict significance as an item rewriting system, Full formal proofs are supported. In fact, after the semantics are defined, first use the kompile tool to compile the semantics, the K framework will automatically generate the corresponding interpreter, and automatically support model checking and symbolic execution analysis for the program, and the...

Abstract

The invention provides a program vulnerability analysis method based on executable formal semantics of a Go language, which comprises the following steps of: (1) studying an expanded barkes normal form officially given by the GO language, and providing a method for converting GO [EBNF] into a general barkes normal form in combination with a BNF grammar format supportable by a K framework to obtain GO [BNF]; (2) defining an executable semantic GO [KS] of the Go language based on rewriting logic by applying a K framework according to the characteristics of the GO [BNF] and the Go language; (3) analyzing the correctness of GO [KS] by adopting a method based on test cases, separately executing the test cases in the K framework and the IntelliJ IDEA tool, and analyzing the correctness of semantics by comparing the consistency of the results of the test cases; and (4) based on the K framework, searching vulnerabilities of the Go program by applying GO [KS]. Integrity of semantics of the Go language is improved, and analysis of program vulnerabilities is realized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a program vulnerability analysis method based on Go language executable formal semantics. Background technique [0002] The Go language is an open-source compiled programming language launched by Google in 2009, also known as GOLang, developed from the C language and designed for concurrency. It not only has the simplicity and efficiency of C, but also the cross-platform, A series of advantages such as the convenience of python, and the efficient concurrency of programs can be realized based on coroutines (goroutines) and channels (channels), in which coroutines are responsible for executing codes, and channels are responsible for passing events between coroutines. For the assignment of coroutine tasks And scheduling is done by the runtime itself. In addition, the Go language also has a garbage collector, which can automate memory management. Its strong static typing feature a...
