Design of attribute-based access control model in collaborative grid environment

Attribute Based Access Control for Grid Computing

Grid systems, which are composed of autonomous domains, are open and dynamic. In such systems, there are usually a large number of users, the users are changeable, and different domains have their own policies. The traditional access control models that are identity based are closed and inflexible. The Attribute Based Access Control (ABAC) model, which makes decisions relying on attributes of r...

A combination of semantic and attribute-based access control model for virtual organizations

A Virtual Organization (VO) consists of some real organizations with common interests, which aims to provide inter organizational associations to reach some common goals by sharing their resources with each other. Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex ...

Privacy-preserving Attribute-based Access Control in a Grid

Privacy Protection of Grid Service Requesters through Distributed Attribute Based Access Control Model

In Grid service environments, traditional identity based access control models are not effective, and access decisions need to be made based on service requesters’ attributes. All of previous attribute based access control (ABAC) models are lacking in protection of users’ privacy because in these models, access control decisions are made by providing the service provider with user attributes. T...

Research on access control in grid environment

Role-Based Access Control, for short RBAC, is a security technology that ensures system resources can not be accessed by non-authorized users. It can be used in network security and works well for grid security as well. Based on the research of RBAC model at present the paper proposes a role-based access control model in grid environment. The model still discusses the issues of role authorizati...
