Web服务组合安全性检测对提高Web服务组合在复杂网络环境下的安全性具有重要意义。针对Web服务组合安全检测存在的问题,提出了一种Web服务组合安全性动态检测框架,并对其中的服务组合流程建模技术、安全模型以及安全检测算法等关键技术进行了详细分析,最后通过实例进一步说明该框架能够实现安全性检测的基本功能。 Web service composition security testing is of great significance to improve the security of Web service composition in complex network environment. Aiming at the existing problems of security detection of Web service composition, this paper proposes a dynamic detection framework of Web service composition security and analyzes the key technologies such as service composition flow modeling technology, security model and security detection algorithm in detail. Finally, The examples further illustrate the basic functions that the framework can implement for security detection.
