Commonly known access control systems respond to users' requests to perform actions on protected objects by giving binary answers such as permit or deny. The decisions are taken on the basis of access control policies, where the risk of allowing access is not necessarily taken into explicit consideration. In this paper, we introduce RBACR model (Role Based Access Control Model with Risk), in which...
There is a need for research on the scientific base and engineering requirements for building trustworthy systems in dynamic environments. To address this need, we study risk analysis for access control from the viewpoint of trust and demonstrate how to extend access control architectures to incorporate trust-based reasoning. We present a theoretical model which allows to reason about and manage risk...
We present a risk management framework which allows to reason about and manage risk for role based access control systems. The framework expresses essential characteristics of risk management in dynamic environments, and can be used for assessing risk and decision making; it is flexible, and able to handle different access control requirements. This framework provides a basis for designing and implementation...
The paper presents a novel Multi-Resolution Model (MRM) of Logistics Location based on the theory of Multi-Resolution Modeling. Using MRM simulation thoughts, it points out the necessary of MRM of Logistics Location by analyzing the key technology of MRM. MRM utilizes Cost - Revenue model(C-R) based on Fuzzy Multiple Attribute Hierarchical Macro Location model (FMAHML) in macroscopic and mesoscopic...
Situation awareness (SA) has been received much attention from human factors and ergonomics community during the past two decades. Team working plays a vital role in complex dynamic situations, increasing requirements for sharing perceptions and comprehension of a situation among team members and improving team situation awareness have been merged. This paper presents a team SA measurement (TSAM)...
