【摘要】 服务流的结构信息必须在流中各结点间传递,信息明码化必然带来敏感信息的外泄,由此产生的安全隐患将导致利益竞争集中某些个体利益受损.为了在保证结点并行运营的同时兼顾其敏感信息安全,文中提出了支撑安全的动态服务流定义,设计了非敏感量依赖树和敏感量依赖树构造算法,对同步库所中的依赖表达式进行敏感变量分离,生成了针对不同对象的依赖表达式树;同时,构造同步智能体,管理该结构信息发布,以实施基于安全的动态服务流管理.实验结果表明系统在兼顾动态运营的同时,也保证了来自各利益体子服务的信息安全.更多还原

【Abstract】 In order to avoid the benefit loss of certain individuals in the benefit competition set due to the sensitive information leakage resulting form the flow of service structure information in all nodes,and to ensure the parallel operation of nodes with high information security,this paper defines a dynamic Web service flow,proposes the non-sensitiveTree and sensitiveTree algorithms to separate sensitive variables from the dependence expression of simul-taneous place,and designs dependence expression trees for different objects.Afterwards,a synchronous agent is constructed to manage the information publishing,thus implementing the management of dynamic service flow with security.Experimental results show that the proposed system can not only manage the dynamic operation but also guarantee the information security of services of each benefit individual.更多还原
