UAV Secure Downlink NOMA Transmissions: A Secure Users Oriented Perspective

Secure Communications in NOMA System: Subcarrier Assignment and Power Allocation

Secure communication is a promising technology for wireless networks because it ensures secure transmission of information. In this paper, we investigate the joint subcarrier (SC) assignment and power allocation problem for nonorthogonal multiple access (NOMA) amplify-and-forward twoway relay wireless networks, in the presence of eavesdroppers. By exploiting cooperative jamming (CJ) to enhance ...

Aspect-Oriented Secure Connectors for Implementation of Secure Software Architecture

This paper describes aspect-oriented secure connectors for implementing secure software architecture for distributed business applications. A secure connector for secure software architecture can be designed separately from application business components by considering different communication patterns between the components as well as security services required by application components. In th...

A Multilevel Secure Object- Oriented Data Model

Recently, several security models have appeared in the literature dealing with mandatory access controls in object-oriented databases. While some of them are of considerable interest and merit (see the later section " Review of relevant research " for a discussion), they seem to lack intuitive appeal because they do not appear to model security in a way that takes full advantage of the object-o...

SODA: A secure object-oriented database system

This paper describes a security model for object-oriented systems. The model supports a flexible data classification policy based on inheritance. The classification policy allows for a smooth transition bctwccn rigid classification rules and unlimited polyinstantiation. The security model treats the data model as well as the computational model of object-oriented systems allowing more flexibili...
