Safe Dynamic Composition and Secure Execution of Software Based on Static Analysis and Execution Monitoring

行为接口规范语言，如Java建模语言（JML），可用于指定程序模块的行为。我们已经开发了一个行为接口规范语言艾草，JML的扩展。艾草提供了一种新的模块化机制，称为断言方面，可以捕获断言之间的横切属性。在本研究中，我们简要地解释了断言方面的概念和艾草的设计，然后我们展示了一个示例规范。通过比较规范的JML对应，我们表明，使用断言方面澄清了大型，复杂的规范，大大简化了规范中的每个断言。

Behavioral interface specification languages, such as Java Modeling Language (JML), can be used to specify the behavior of program modules. We have developed a behavioral interface specification language Moxa, an extension of JML. Moxa provides a new modularization mechanism called assertion aspect that can capture the crosscutting properties among assertions. In this resarch, we briefly explain the notion of assertion aspects and the design of Moxa, and then we show an example specification. By comparing the specification to its JML counterpart, we show that the use of assertion aspects clarifies the large, complex specification and greatly simplifies each assertion in the specification.
