中文摘要：

基于构件接口分离原则和动态软件体系结构技术，提出了一种支持网络动态重构的可信构件模型，对构件构造和组装进行了分析，并提出了可信数据安全封装机制。基于感知、决策和执行分离机制，构件模型可以支持构件重构，通过容器对构件数据进行安全封装，构件模型可以检测和阻止恶意构件的非法操作，保护构件间的数据安全传递。实现了支持可信构件模型的容器原型，实验表明，使用该模型可进行构件连接拓扑关系的重构，可及时发现恶意构件并暂停构件运行，提高了节点的可信性。

英文摘要：

Based on principles of the separation of concerns and the dynamic software architecture （DSA） technology, a component model named TCM （trustworthy component model） was proposed. Formation and assemblage of components were analyzed, then a trustworthy data security sealing mechanism was proposed. By sealed the data, the TCM not only support reconfiguring components, but also prevent component hostility operation, which can destroy the data transmission. A container prototype was implemented, and experimental applications were implemented to validate this approach. The results show that this model can change the topology of components and find out the hostility components, which improve the trustworthy of reconfigurable flexible network node.
