Dynamic Authorization Support in Large Distributed Systems
Traditionally, a system can only be trusted after it has been formally proven trustworthy. However, due to the inherent complexity of distributed systems and the limitation of formal methods, trust based on factors other than formal logic verification has to be included in designing and developing …

Automated Multiparty Authorization in Open Distributed Systems
… identity-based access control often bases its authorization solely on the authentication of a user to a known identity, and becomes unsuitable for open systems, where the interacting parties could be total strangers to each other, yet still have the need for rapid and secure resource sharing. …

Efficient Automated Security Analysis of Complex Authorization Policies
… security requirements need to be ensured by authorization policies for increasingly complex and large applications. As a consequence, designers need to understand such policies and ensure that they meet the desired security constraints while administrators must also maintain them so as to …

A DSL for managing Capability-Driven Authorization policies
Τα συστήματα εξουσιοδότησης που χρησιμοποιούνται στις σύγχρονες εφαρμογές δυσκολεύονται να γεφυρώσουν το χάσμα μεταξύ των επιχειρηματικών λειτουργιών και των τεχνικών μηχανισμών ελέγχου πρόσβασης. Οι παραδοσιακές προσεγγίσεις διασκορπίζουν την λογική εξουσιοδότησης σε όλο τον κώδικα της εφαρμογής, …

Two factor authentication and authorization in ubiquitous mobile computing
… A lightweight holistic authentication and authorization scheme is presented for this typical wireless scenario. It is shown that either SIM or Kerberos authentication has its limitations. A two-factor authentication method SIM-based Kerberos authentication is developed to implement the …

Towards Practical and Secure Decentralized Attribute -Based Authorization Systems
We first show that existing ABAC theory does not properly account for the asynchronous nature of open systems, which allows attackers to subvert these systems by forcing decisions to be made using inconsistent system states. To address this, we develop provably-secure and lightweight consistency …

PRIMA - Privilege Management and Authorization in Grid Computing Environments
… systems require more powerful and more flexible authorization mechanisms to realize fine-grained access-control of resources. Computational grids are increasingly used for collaborative problem-solving and advanced science and engineering applications. Usage scenarios for advanced grids require …

THE PROGRAM PATHING TRUST MODEL FOR CRITICAL SYSTEM PROCESS AUTHORIZATION
Since computers are relied upon to run critical infrastructures – from nuclear power plants to electronic battlefield simulations – the concept of a “trusted” or tamperproof system has become even more important. Some applications have become so critical that it is imperative that they run as …

True love stories : the tropical production and authorization of meaning
The reason that modern love is not postmodern is that it insists on being psychological. The reason that sociology treats of love so poorly is that it insists on not being poststructuralist. This project inverts this double steadfastness, in order to sociologize love as a production of its own …

Dynamic Role Lease Authorization Protocol for a Distributed Computing System
… adapt the RBAC concept to Grids and focus on the authorization and verification of the dynamic factors or contexts of a user, such as time, location, rank, etc. Some applications also allow administrators to change the policies during the authorization process, but they did not handle the …

A generic framework for process execution and secure multi-party transaction authorization
… sensitive transactions, a highly secure authorization scheme supporting asynchronous multi-party transaction authorization must be available within process management systems. Therefore, along with the ePVM framework, this thesis presents a novel approach for secure remote multi-party …

Theological and Liturgical Dimensions of Ecclesial Authorization for U.S. Catholic Lay Ecclesial Ministers
This work provides steps toward a practical understanding of the changing ministerial relationships in the U.S. Catholic Church given the rapid increase in lay ecclesial ministers ("LEMs") and decline in ordained priests. New ecclesial relationships develop through shifts in ecclesial ministry; …

The SUDO Framework: For Data Organization And Efficient Query Authorization For NoSQL Databases
… on weaving queries and policies for efficient authorization. AReBAC is also accompanied by GP-Eval, a query evaluation algorithm that surprisingly performs orders of magnitudes faster than the Cypher query evaluation engine provided by Neo4j, and introduces a new constraint satisfaction …

Farewell to arms: a plan for evaluating the 2001 authorization for use of military force and its alternatives
On September 14, 2001, Congress passed the 2001 Authorization for Use of Military Force (AUMF). Over the past 13 years, the AUMF has served as the primary legal foundation for the use of force against terrorist organizations and other counterterrorist operations. Since its passage, threats facing …

Optimization model applying lean Six Sigma for the reduction of time in the granting of authorization titles for mining projects
Según el Ministerio de Energía y Minas (2024), en el 2023, el subsector minero representó el 10,40% del Producto Bruto Interno (PBI) de Perú, mientras que, en el 2024, las exportaciones de minerales (plata, cobre, plomo y zinc) alcanzaron los US$3,1 millones. En enero de 2024, la inversión minera …
