摘要：Various credential based approaches have been proposed for realizing access control on shared data sources. These approaches use various types of credentials like identity certificates, attribute certificates, authorization certificates etc. Different credentials are found to be suitable in different conditions. The aim of this paper is to develop an access control methodology that not only enables immediate and open access to shared data by competent users but also provides fine grained access control on the domain confined data. The concept of standard credential is introduced which is a general purpose credential and can grant easy and fast access to variety of data sources across multiple domains. In this methodology, access control policy is defined using various types of credentials. Use of different types of credentials simplifies the specification of access control policy and provides more granular access control.
