Bayesian Differential Privacy through Posterior Sampling

Christos Dimitrakakis, Blaine Nelson, and Zuhe Zhang +2

Differential privacy formalises privacy-preserving mechanisms that provide access to a database. We pose the question of whether Bayesian inference itself can be used directly to p…

Near-Optimal Blacklisting

Christos Dimitrakakis, Aikaterini Mitrokotsa

Many applications involve agents sharing a resource, such as networks or services. When agents are honest, the system functions well and there is a net profit. Unfortunately, some…

Expected loss analysis of thresholded authentication protocols in noisy conditions

Christos Dimitrakakis, Aikaterini Mitrokotsa, Serge Vaudenay

A number of authentication protocols have been proposed recently, where at least some part of the authentication is performed during a phase, lasting rounds, with no error corr…

Shedding Light on RFID Distance Bounding Protocols and Terrorist Fraud Attacks

Pedro Peris-Lopez, Julio C. Hernandez-Castro, Christos Dimitrakakis +2

The vast majority of RFID authentication protocols assume the proximity between readers and tags due to the limited range of the radio channel. However, in real scenarios an intrud…

Towards an Effective Intrusion Response Engine Combined with Intrusion Detection in Ad Hoc Networks

Aikaterini Mitrokotsa, Nikos Komninos, Christos Douligeris

In this paper, we present an effective intrusion response engine combined with intrusion detection in ad hoc networks. The intrusion response engine is composed of a secure communi…
