| 摘 要： | Web服务流具有动态、分布、松散耦合的特点，这导致Web服务流的配置和管理有别于传统工作流的管理。在管理过程中，服务流结构信息的明码化必然产生敏感信息的安全隐患，从而导致流中某些个体利益受损。文章首先提出了支撑安全的动态服务流定义，进而设计算法non-sensitiveTree、sensitiveTree对同步库所中依赖表达式进行敏感变量分离，并构造同步智能体实施基于安全的动态服务流管理。

| Abstract: | Web service-flow having dynamic, distributed and flexible characteristic makes the on-line management different from the classical workflow. In the management process, the information of service-flow structure will have sensitive information security risks, resulting in some individual interests of the flow may suffer. This paper first gave the definition of the dynamic security service-flow, and then two algorithms were designed to separate the sensitive variables from the the dependence expression of simultaneous place, that would help the synchronous agent to do the management of service-flow safely. |
