Proceedings of the 19th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2011
As mobile computing devices are becoming increasingly dominant in enterprise and government organizations, the need for fine-grained access control in these environments continues to grow. Specifically, advanced forms of access control can be deployed to ensure authorized users can access sensitive resources only when in trusted locations.

AT-RBAC: An Authentication Trustworthiness-Based RBAC Model
2004In current operating systems, the strength of authentication mechanism does not work on the authorization of the user, which leaves the system security compromise that the user who has passed weak authentication mechanism may have many access rights. This paper firstly puts forwards the thought of authentication trustworthiness, the aim is to give each

RBAC-MAS and SODA: Experimenting RBAC in AOSE
2009Role-Based Access Control models are currently considered as the most effective approach for engineering access control systems. In this paper we experiment their application in the context of Multi-Agent Systems (MAS), by discussing the design of an access control system with an agent-oriented methodology such as SODA.

Administration of an RBAC system
37th Annual Hawaii International Conference on System Sciences, 2004. Proceedings of the, 2004Recently RBAC (role-based access controls) was found to be among the most attractive solutions for providing access control in Web-based e-commerce and e-government applications. Usually, such systems involve a huge number of heterogeneous users working with the systems under different rights and obligations. In an RBAC authorization and access control

CT-RBAC: A Temporal RBAC Model with Conditional Periodic Time
2007 IEEE International Performance, Computing, and Communications Conference, 2007Many emerging applications show the need for a fine-grained context based access control requirements. The generalized temporal RBAC model has been proposed to capture fine-grained time-based access control requirements using periodic time expression to capture recurring intervals of time.

LoT-RBAC: A Location and Time-Based RBAC Model
2005Recent growth in location-based mobile services has introduced a significant need for location and time-based access control to resources. High mobility of the users and services in the emerging mobile applications in particular make the issue of controlling who can access what information and resources from which locations a daunting challenge ...

A graph-based formalism for RBAC
ACM Transactions on Information and System Security, 2002Role-Based Access Control (RBAC) is supported directly or in a closely related form, by a number of products. This article presents a formalization of RBAC using graph transformations that is a graphical specification technique based on a generalization of classical string grammars to nonlinear structures.

Contract RBAC in cloud computing
Journal of Supercomputing, 2013Cloud computing is a fast growing field, which is arguably a new computing paradigm. In cloud computing, computing resources are provided as services over the Internet and users can access resources based on their payments. The issue of access control is an important security scheme in the cloud computing.

This paper focuses on recommending the usage of the Role-Based Access Control (RBAC) model to define the users’ security roles, permissions, authorization, and role hierarchy to access the SCADA system. Achieving the desired level of authorization and access control will involve integrating the secur ity system with SCADA operations and building role ...

SC-RBAC: A Smart Contract based RBAC Model for DApps
2019Blockchain technology with its non-centralized, transparent, trustful, traceable and tamper-resistant features draws more and more attention both in commercial and scientific area. Smart contracts and DApps (Decentralized Applications) are programs naturally running automatically on blockchain. Access control is a principle that regulates the access to
