| 摘 要： | 访问控制是信息安全中的一种重要保护机制。访问控制矩阵规定了主体对客体的访问权限。传统的访问控制矩阵是静态的,本文描述了一种基于Petri网的工作流动态访问控制机制,它根据工作流的状态来确定主体对客体的访问权限。通过对比,动态访问控制机制使得访问控制权限更加细分,从而具有更高的安全性。

| Abstract: | Access control is an important protection mechanism for information security. Access control matrices grant subjects access authorizations to objects. Access control matrices in common use are static. A dynamic access control mechanism is shows through workflow based on Petri nets. According to the state of workflow, the mechanism can get the fractionized access authorizations in contrast with the access control mechanism in common use. Therefore, the dynamic control mechanism can provide with rigorous security. |
