摘要: 软件的形式化验证是保障软件可证明性、可靠性和安全性的重要手段,但传统形式化验证脚本的生成过程复杂且需要形式化验证专家的大量手工验证。为提高证明效率,构建一种自动证明模型,并在此基础上提出语义自动规约算法以及对所规约的语义自动生成证明脚本的算法。利用C++和Python并通过交互式定理证明器Isabelle 2017在基准数据中随机选择10个程序进行测试,结果表明,与完全人工操作相比,该算法具有较高的验证效率,可实现顺序语句块的自动化规约与验证。

关键词: 自动形式化规约, 自动化验证, 定理证明器, 交互式定理, 形式化验证

Abstract: Formal verification of software is an important means to guarantee the provability,reliability and security of software, but the generation process of traditional formal verification script is complex and requires a lot of manual verification of formal verification experts.In order to improve the efficiency of proof,this paper constructs an automatic proof model,and on this basis,proposes a semantic automatic specification algorithm and its automatic generation algorithm for generating proof scripts.Using C++ and Python and randomly selecting 10 programs in the benchmark data by the interactive theorem prover Isabelle 2017 to run the test,results show that compared with the fully manual operation,the algorithm has higher verification efficiency,and can implement automatic specification and verification of sequential statement.

Key words: automatic formal specification, automatic verification, theorem prover, interactive theorem, formal verification
