基于SMT的LTL规范验证及其在服务可替代性验证中的应用
SMT-based Verification of LTL Specifications with Integer Constraints and its Application to Runtime Checking of Service Substitutability
摘要：
在基于服务的应用程序的执行过程中出现的一个重要问题涉及确定是否可以用具有不同接口的服务来替换正在运行的服务的能力，例如，如果前者不再可用。标准有界模型检验技术可用于执行此检查，但它们必须能够非常快速地提供答案，以免检查妨碍应用程序的可操作性，而不是帮助它。当考虑会话服务时，问题变得更加复杂，即，服务，公开其中具有输入/输出数据依赖关系的操作。在本文中，我们介绍了一个形式化验证技术的线性时序逻辑，允许用户在公式中的整数变量的约束的扩展。这种技术适用于会话服务的可替代性问题被证明是相当快，比现有的内存占用更小。
英文摘要：
An important problem that arises during the execution of service-based applications concerns the ability to determine whether a running service can be substituted with one with a different interface, for example if the former is no longer available. Standard Bounded Model Checking techniques can be used to perform this check, but they must be able to provide answers very quickly, lest the check hampers the operativeness of the application, instead of aiding it. The problem becomes even more complex when conversational services are considered, i.e., services that expose operations that have Input/Output data dependencies among them. In this paper we introduce a formal verification technique for an extension of Linear Temporal Logic that allows users to include in formulae constraints on integer variables. This technique applied to the substitutability problem for conversational services is shown to be considerably faster and with smaller memory footprint than existing ones.
