Policy-driven role-based access management for ad-hoc collaboration

Gail-Joon Ahn, Jing Jin, Mohamed Shehab
2012 Journal of Computer Security  
In this paper, we propose a comprehensive, integrated and implemented access management framework, called RAMARS, for secure digital information sharing in ad-hoc collaboration.  ...  The dynamic nature and unique sharing pattern in ad-hoc collaboration poses great challenges for security services to accommodate both access control and trust management requirements in providing controlled  ...  management for ad-hoc collaboration 235 Ahn et al. / Policy-driven role-based access management for ad-hoc collaboration Ahn et al. / Policy-driven role-based access management for ad-hoc collaboration  ...

Unraveling decentralized authorization for multi-domain collaborations

Hannah K. Lee
2007 2007 International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom 2007)  
First of all, the solutions address particular types of multi-domain collaborations such as Virtual Organization or resource-sharing collaborations.  ...  This approach appears to be more suitable to produce a more efficient and elegant authorization solution for the majority of multi-domain collaborations.  ...  Role-based trust management (RT) combines the strengths of role-based access control and trust management systems and is capable of expressing attribute-based access control [25] .  ...

A Survey on Trust Aware Security and Scheduling in Traditional and Ad Hoc Grids

Slavomír Kavecký, Penka Martincová
2016 International Journal of Computer Applications  
The ad hoc grid infrastructure was proposed as a consequence of the need for the short-term collaborations.  ...  The grid infrastructure has emerged as a technology supporting long-term collaboration utilizing shared resources spread across multiple administrative domains.  ...  The motivation for ad hoc grid development is its ability to handle short-term collaborations.  ...
