多域环境下的访问控制是域间互操作必须要解决的重要问题。针对数据交换平台项目中政府机构存在的地域和职能域不同的管理级别,构造了地域职能域融合确定信任域的方法,并通过制定基于角色的访问控制策略实现对跨域数据交换中心系统中域资源的不同权限安全访问。
Access control in multi-domain environment is an important issue that must be solved in inter-domain interoperability. Aiming at the different management levels of government agencies in the data exchange platform project, this paper constructs the method of determining the trust domain by the integration of the domain function domains and establishes the role-based access control policy to implement the cross-domain data exchange center system domain Different access to resources for secure access.
