摘要
论文针对目前工作流协同机制中自组织和自适应策略表达能力差等缺陷,探讨了基于树结构的加密协调模型的一种新构建方法.首先,论文描述了基于树结构的加密协调模型并剖析总结了现有体系制约这一模型构建的多种原因;然后以电子公文的处理为例,基于有色Petri网的相关理论,提出了密钥驱动的一种新建模元素.进而,原系统在功能增加的同时API接口并没有发生改变,便于现有使用产品的技术升级.
To tackle the problem which is that the present work - flow systems can＇ t express the policy of self - organizing and self - adapting,the paper has researched on the new method for modeling the work - flow encryption coordinaton based on the tree structure.At first,the paper has built the encryption coordination model based on the tree structure and analyzed the cases that the present systems are difficult in modeling it. Then, referring from the theory of colored petfi net, the new method has emphasized to design the key management. The modeled work - flow has higher performance characteristic without changing the link with API so that it can satisfy the cooperation computation better.
