Security models

In this study, we propose a NOMA communication model combined with linear array antennas for the purpose of enhancing physical layer security. We introduce a model of 4 nodes: transmitter node S, receiver node D1, receiver node D2, eavesdropping node E.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

Several studies have been carried out by optimising only the cost. They have not considered some other risk factors such as political and economic factors in their modelling. Currently, there is no generalised model available to determine the optimal sourcing locations incorporating important factors including risks in international LNG trading. In this study, 12 risk factors were taken into consideration to evaluate the risk.

Apart from trying to shed sufficient light on the dominant capital structure in South Africa, this study attempts to answer the question of: what is the role of capital structure in firm valuation? In addition, the role of other market and economic variables like taxation will be assessed using a regression model and data drawn from financial markets.

We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called \cryptographic hash functions". The main result of this paper is a negative one: There exist signature and encryption schemes that are secure in the Random Oracle Model, but for which any implementation of the random oracle results in insecure schemes.

[ Team LiB ] Understanding Outlook's Security One of Outlook's strengths is its programmability. Outlook supports VBA, enabling you to use procedures to automate many mundane tasks. When you need more than VBA provides, you can install COM add-ins to provide features that Microsoft didn't build into Outlook. A Component Object Model (COM) add-in is an application that uses the host program's object model to access the host program's interface. COM add-ins add features missing from the program or improve on existing features. Extended Reminders (www.slovaktech.
