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…
Statistical Decision Making for Authentication and Intrusion Detection
Christos Dimitrakakis, Aikaterini Mitrokotsa
User authentication and intrusion detection differ from standard classification problems in that while we have data generated from legitimate users, impostor or intrusion data is s…
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…
