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.

The Importance of Delegation of Authority, Budget Allocation and Leadership in Improving Performance
The International Journal of Science and Society, 2020This study discusses the influence of delegation of authority, budget allocation and leadership to the performance of sub-districts in Garut Regency, West Java Province, Indonesia. This research uses a quantitative approach by collecting data in the form

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.

Speaking on Behalf of: Representation, Delegation, and Authority in Computational Text Analysis
AAAI/ACM Conference on AI, Ethics, and Society, 2019Computational tools can often facilitate human work by rapidly summarizing large amounts of data, especially text. Doing so delegates to such models some measure of authority to speak on behalf of those people whose data are being analyzed.

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.
