Physical layer security: Friendly jamming in an untrusted relay scenario [PDF]
2016 24th European Signal Processing Conference (EUSIPCO), 2016 This paper investigates the achievable secrecy regions when employing a friendly jammer in a cooperative scenario employing an untrusted relay. The untrusted relay which helps to forward the source signal towards the destination, could also be regarded as a potential eavesdropper.

Criminology, Volume 64, Issue 3, Page 698-733, August 2026.Abstract We investigate how the affordances of an online context shape the processes of social learning. Using a dataset of more than 11,000 posts from the fraud subdread on the dark web forum Dread, we examine how affordances of platform governance, connectivity, anonymity, invisibility, asynchronicity, and limited oversight influence the components ...

Performance Evaluation of Privacy Models for Data Streams on the Edge
Internet Technology Letters, Volume 9, Issue 3, May/June 2026.ABSTRACT Recent advances in edge computing enable data stream privacy enforcement directly on resource‐constrained devices, reducing latency and the exposure of sensitive information. In this paper, we extend and validate our previously proposed privacy‐enforcing framework, which allows high‐level privacy policies to be expressed as chains of triggers ...
