Grid Computing involves heterogeneous computers and resources, multiple administrative domains and the mechanisms and techniques for establishing and maintaining effective and secure communications between devices and systems. Both authentication and authorization are required. Current authorization models in each domain vary from one system to another, which makes it difficult for users to obtain authorization across multiple domains at one time.

520 $a Grid Computing involves heterogeneous computers and resources, multiple administrative domains and the mechanisms and techniques for establishing and maintaining effective and secure communications between devices and systems. Both authentication and authorization are required. Current authorization models in each domain vary from one system to another, which makes it difficult for users to obtain authorization across multiple domains at one time.
520 $a We propose an enhanced security architecture to provide support for decentralized authorization based on attribute certificates which may be accessed via the Internet. This allows the administration of privileges to be widely distributed over the Internet in support of autonomy for resource owners and providers. In addition, it provides a uniform approach for authorization which may be used by resource providers from various domains. We combine authentication with the authorization mechanism by using both MyProxy online credential repository and LDAP directory server.
520 $a In our architecture, we use MyProxy server to store identity certificates for authentication, and utilize an LDAP server-based architecture to store attribute certificates for authorization. Using a standard web browser, a user may connect to a grid portal and allow the portal to retrieve those certificates in order to access grid resources on behalf of the user. Thus, our approach can make use of the online credential repository to integrate authentication, delegation and attribute based access control together to provide enhanced, flexible security for grid system.
