A Secured Model for Resource Access in Grid Environment
Grid computing provides a way to execute applications over autonomous, distributed and heterogeneous nodes. The main goal of grid technology is to allow sharing of resources and services under a set of rules and policies, which govern the conditions for access to the resources. This paper reviews the state of security and access control for resources in grid environment and presents a secured model for resource access in grid environment.
Analysis of Decentralized & Diverse Access Control (DDAC) Architecture
Access control refers to securing access to the resources and allowing access up to some defined level. This paper presents various approaches implementing access control in an open domain and carries an analysis of decentralized and diverse access control (DDAC) architecture. The DDAC architecture eliminates the role of centralized authority for managing and issuing users’ credentials. It allows the users to keep the right of disclosure of their attributes under the sole control of them and also ensures that the users are not able to modify the confidential credentials which have been registered and verified by various trusted attribute providers. This paper explains the metrics for carrying the analysis and then presents a theoretical and experimental analysis of the DDAC architecture.
