当前的万维网服务体系结构与一些 stubbornproblems 被面对，并且安全问题成为限制万维网服务的 extensiveapplication 的瓶颈之一。在有消息水平安全的比较运输水平以后，运输水平安全的 thelimitation 清楚地变得。然后根据分析 messagelevel 安全，特别 WS 安全， XML 安全协议被采用保证 messagelevel 安全。因为 WS 安全是一新 protocoljointly 由微软和 IBM amongthese XML 安全发展了协议，和 WS 安全机制的安全标志机制被改进，与安全标志类型增加了一张桌子。并且向前由多重安全标志 isput 组成保证消息传播的安全的一个新模型。

英文摘要：

Current Web services architectures are confronted with a few stubborn problems, and the security problem becomes one of the bottlenecks that restrict the extensive application of Web service. After compared transport level with message level security, the limitation of transport level security became clearly. And then on the basis of the analysis message level security, especially WS-Security, XML security protocol was adopted to guarantee message level security. Because WS-Security is a new protocol jointly developed by Microsoft and IBM among these XML security protocols, and a security-token mechanism of WS-Security mechanism was improved, added a table with security-token types. And a new model consisting of multiple security-token is put forward to guarantee the security of message transmission.
