Parallel Access Control Model in Cross-Domain Grid Computing Environment

2. Access Control Related Works

The authorization process in grids implies mainly the technique to control the access of users to various resources (Bhatia, 2013). But the lack of an appropriate authorization process leads to a large loss of data. The traditional techniques of authorization were based on the access control lists where the user whose name appears in the list is authorized to reach the grid with the privileges associated with the names (Khider, Osman & Sherkat, 2010). In this technique, the resource provider has to maintain authorization decisions for every user, which is a very time consuming and non-scalable solution. Recently, a large number of access control models have been proposed in distributed environments.
