Adding support to XACML for multi-domain user to user dynamic delegation of authority [PDF]
International Journal of Information Security, 2009 . We describe adding support for dynamic delegation of authority between users in multiple administrative domains, to the XACML model for authorisation decision making.

Adding Support to XACML for Dynamic Delegation of Authority in Multiple Domains [PDF]
Lecture Notes in Computer Science, 2006 In this paper we describe how we have added support for dynamic delegation of authority that is enacted via the issuing of credentials from one user to another, to the XACML model for authorisation decision making.

Delegating Revocations and Authorizations
2008Delegation models based on role-based access control (RBAC) management have been known as flexible and efficient access management for data sharing on distributed environment. Delegation revocations are a significant functionality for the models in distributed environment when the delegated roles or permissions are required to get back.

Supporting E.cient Authorization in Delegation with Supervision
11th International Conference on Parallel and Distributed Systems (ICPADS'05), 2006Delegation is commonly used in organizations to transfer some permission by one user to another user. However, most existing delegation schemes do not support supervision, which allows the delegators to retain control over how the delegated permission can be exercised. In this paper, we describe how to support efficient authorization in delegation with

Evaluation of Authorization with Delegation and Negation
2003Access evaluation is a significant issue in any intelligent information system. In this paper, we develop a logic programming based approach for decentralized authorization delegations in which users can be delegated, granted or forbidden some access rights.

Resolving Conflicts in Authorization Delegations
2002In this paper, we first discuss some drawbacks of the existing conflict authorization resolution methods when access rights are delegated, and then propose a flexible authorization model to deal with the conflict resolution problem with delegation. In our model, conflicts are classified into comparable and incomparable ones.

Delegated Authenticated Authorization for Constrained Environments
2014 IEEE 22nd International Conference on Network Protocols, 2014Smart objects are small devices with limited system resources, typically made to fulfill a single simple task. By connecting smart objects and thus forming an Internet of Things, the devices can interact with each other and their users and support a new range of applications.

A Classification of Delegation Schemes for Attribute Authority
2007Recently assertions have been explored as a generalisation of certificates within access control. Assertions are used to link arbitrary attributes (e.g. roles, security clearances) to arbitrary entities (e.g. users, resources). These attributes can then be used as identifiers in access control policies to refer to groups of users or resources.

Implementing Authorization Delegations Using Graph
2006Graph-based approach to access control models have been studied by researchers due to its visualization, flexible representation and precise semantics. In this paper, we present a detailed graph-based algorithm to evaluate authorization delegations and resolve conflicts based on the shorter weighted path-take-precedence method.
