摘要
网格中大量用户共享不同组织提供的资源。传统的网格授权控制方式已无法适应具有大量用户的模式。该文在实际需求下建立了一个轻量级访问控制服务DACS。DACS将VO用户划分为不同的等级,资源只需对VO用户按级别进行整体授权。
Grid is composed of several thousands of users from different organizations sharing their resources. Controlling access to these resources is a difficult problem and traditional access authorization is not applicable to a large scale environment. This paper describes a lightweight authorization service developed to solve this problem in the project requirements： data access control service （DACS）. DACS divide VO users into different levels and resources only maintain access control policies to all users in same level as a whole.
