TL;DR: This paper proposes a unified framework together with a single parametric algorithm that supports all the legitimate combinations simultaneously, based on four conflict resolution policies, and validate the approach by testing the algorithm against both real data and synthetic examples.

Abstract: While some authorization models support either positive or negative authorizations, hybrid frameworks take advantage of both authorizations. Resolving authorization conflicts is quite a challenge due to the existence of sophisticated inheritance hierarchies and the diversity of ways to combine resolution policies. Some researchers have addressed conflict resolution for tree-structured hierarchies, and others have applied a simple conflict resolution policy. The challenge is to combine several policies and to support sophisticated structures in one single framework. This paper proposes a unified framework together with a single parametric algorithm that supports all the legitimate combinations simultaneously, based on four conflict resolution policies. We validate our approach by testing the algorithm against both real data and synthetic examples to provide extensive experimental results.

Access control administration with adjustable decentralization
Amir H. Chinaei
- 01 Jan 2007
TL;DR: A conflict-free and decentralized access control administration model in which all users are able to retain complete control over their own data while they are also able to delegate any subset of their privileges to other users or user groups is introduced.

Comparison of Access Control Administration Models
Amir H. Chinaei,Ken Barker,Frank Wm +2 more
- 01 Jan 2009
TL;DR: A novel formalism to compare access control administration models based on their expressivity in a) administrative decentralization and b) conflict resolution is proposed, which can intuitively comment on each model in the context of their administrative functionality, performance, and security.

Protection in operating systems
TL;DR: A model of protection mechanisms in computing systems is presented and its appropriateness is argued and it can be shown that this problem is decidable, i.e. there is an algorithm to determine whether a system in a particular configuration is safe.

The role graph model and conflict of interest
TL;DR: This work describes in more detail the reference model for role-based access control introduced by Nyanchama and Osborn, and the role-graph model with its accompanying algorithms, which is one way of implementing role-role relationships.

- 20 May 2003
TL;DR: This paper is the first attempt at describing the XML Web and the documents contained in it and shows that, despite its short history, XML already permeates the Web, both in terms of generic domains and geographically.

TL;DR: A data definition and manipulation language for XML repositories that enables users to perform data management tasks such as creation and deletion of indices, collections and documents and the ability to perform queries, transformations and updates on the documents in the XML repository either singly or across an entire collection.
