为了改进和提高角色访问控制(RBAC)的角色管理与权限配置效能,本文提出了一种基于同构化客体状态适配监控的RBAC扩展模型。该模型在RBAC的角色与权限之间新增设一个基于客体状态的同构化适配监控层,使不同客体状态所对应的角色及其权限建立起关联;并在客体状态发生转换而引起其相关角色和权限变更时,可通过观察者模式正确地及时捕捉、自动回应和动态适配这些转换和变更,以尽可能地避免访问冲突、阻绝非法访问;从而,能对各客体在不同状态下的安全访问与访问安全,实施更有序和高效的敏捷控制。
In order to improve and enhance the role management and privilege allocation of role access control (RBAC), this paper proposes a RBAC extension model based on isomorphic object stateful monitoring. The model adds a new isomorphic adaptive monitoring layer based on object state between role and authority of RBAC to associate the roles and permissions of different object states. When the state of object changes, When the related roles and authorities are changed, these transitions and changes can be correctly and timely captured through the observer mode, and the access and conflict can be avoided as much as possible to prevent illegal access. Thus, each object can be controlled in different states Secure access and access security, and implement more orderly and efficient agile control.
