Social Security: Theoretical Aspects

Social Aspects of Information Security

Social Engineering (SE) threats have constituted a reality for Information Technology (IT) systems for many years. Yet, even the latest editions of the generally accepted Information Security (IS) standards and best practices directives do not effectively address the Social Engineering aspect of IS defences. SE attacks target the human element of IS by exploiting human relations to the maximum ...

Wireless Information-Theoretic Security - Part I: Theoretical Aspects

In this two-part paper, we consider the transmission of confidential data over wireless wiretap channels. The first part presents an information-theoretic problem formulation in which two legitimate partners communicate over a quasi-static fading channel and an eavesdropper observes their transmissions through another independent quasi-static fading channel. We define the secrecy capacity in te...

A Game-Theoretical Approach to Multimedia Social Networks Security

The contents access and sharing in multimedia social networks (MSNs) mainly rely on access control models and mechanisms. Simple adoptions of security policies in the traditional access control model cannot effectively establish a trust relationship among parties. This paper proposed a novel two-party trust architecture (TPTA) to apply in a generic MSN scenario. According to the architecture, s...
