Adding Support to XACML for Dynamic Delegation of Authority in Multiple Domains [PDF]
, 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.

Multilevel access control for video database
Tongxin xuebao, 2012 In regards to the critical issues of classification protecting sensitive information of the data stored in video database,a multilevel access control model for the video database was proposed.A series of algorithms was designed and developed in the model

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

A Calculus for Flow-Limited Authorization: Technical Report [PDF]
, 2016 Real-world applications routinely make authorization decisions based on dynamic computation. Reasoning about dynamically computed authority is challenging. Integrity of the system might be compromised if attackers can improperly influence the authorizing

Comparison of advanced authorisation infrastructures for grid computing [PDF]
, 2005 The widespread use of grid technology and distributed compute power, with all its inherent benefits, will only be established if the use of that technology can be guaranteed efficient and secure. The predominant method for currently enforcing security is

Hidden Signature for DTW Signature Verification in Authorizing Payment Transactions
Journal of Telecommunications and Information Technology, 2023 Traditional use of dynamic time warping for signature verification consists of forming some dissimilarity measure between the signature in question and a set of “template signatures”.

Advanced Security for Virtual Organizations: The Pros and Cons of Centralized vs Decentralized Security Models [PDF]
, 2008 Grids allow for collaborative e-Research to be undertaken, often across institutional and national boundaries. Typically this is through the establishment of virtual organizations (VOs) where policies on access and usage of resources across partner sites

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Towards Integrated Modelling of Dynamic Access Control with UML and Event-B [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 Role-Based Access Control (RBAC) is a popular authorization model used to manage data-access constraints in a wide range of systems. RBAC usually defines the static view on the access rights.
