Generalized Rainbow Differential Privacy

no code implementations11 Sep 2023 Yuzhou Gu, Ziqi Zhou, Onur Günlü, Rafael G. L. D'Oliveira, Parastoo Sadeghi, Muriel Médard, Rafael F. Schaefer

In this framework, datasets are nodes in a graph, and two neighboring datasets are connected by an edge.

Concatenated Classic and Neural (CCN) Codes: ConcatenatedAE

no code implementations4 Sep 2022 Onur Günlü, Rick Fritschek, Rafael F. Schaefer

Small neural networks (NNs) used for error correction were shown to improve on classic channel codes and to address channel model changes.

Secure and Private Source Coding with Private Key and Decoder Side Information

no code implementations10 May 2022 Onur Günlü, Rafael F. Schaefer, Holger Boche, H. Vincent Poor

The problem of secure source coding with multiple terminals is extended by considering a remote source whose noisy measurements are the correlated random variables used for secure source reconstruction.

Secure Joint Communication and Sensing

no code implementations22 Feb 2022 Onur Günlü, Matthieu Bloch, Rafael F. Schaefer, Aylin Yener

For independent and identically distributed states, perfect output feedback, and when part of the transmitted message should be kept secret, a partial characterization of the secrecy-distortion region is developed.

Rainbow Differential Privacy

no code implementations8 Feb 2022 Ziqi Zhou, Onur Günlü, Rafael G. L. D'Oliveira, Muriel Médard, Parastoo Sadeghi, Rafael F. Schaefer

We extend a previous framework for designing differentially private (DP) mechanisms via randomized graph colorings that was restricted to binary functions, corresponding to colorings in a graph, to multi-valued functions.

Function Computation Under Privacy, Secrecy, Distortion, and Communication Constraints

no code implementations11 Jan 2022 Onur Günlü

The problem of reliable function computation is extended by imposing privacy, secrecy, and storage constraints on a remote source whose noisy measurements are observed by multiple parties.

Quality of Service Guarantees for Physical Unclonable Functions

no code implementations12 Jul 2021 Onur Günlü, Rafael F. Schaefer, H. Vincent Poor

A public ring oscillator (RO) output dataset is used to illustrate that a truncated Gaussian distribution can be fitted to transformed RO outputs that are inputs to uniform scalar quantizers such that reliability guarantees can be provided for each bit extracted from any PUF device under additive Gaussian noise components by eliminating a small subset of PUF outputs.

Secure Multi-Function Computation with Private Remote Sources

no code implementations17 Jun 2021 Onur Günlü, Matthieu Bloch, Rafael F. Schaefer

We consider a distributed function computation problem in which parties observing noisy versions of a remote source facilitate the computation of a function of their observations at a fusion center through public communication.

Federated Learning with Local Differential Privacy: Trade-offs between Privacy, Utility, and Communication

no code implementations9 Feb 2021 Muah Kim, Onur Günlü, Rafael F. Schaefer

We consider Gaussian mechanisms to preserve local differential privacy (LDP) of user data in the FL model with SGD.

On Skew Convolutional and Trellis Codes

no code implementations2 Feb 2021 Vladimir Sidorenko, Wenhui Li, Onur Günlü, Gerhard Kramer

Two new classes of skew codes over a finite field $\F$ are proposed, called skew convolutional codes and skew trellis codes.

Secret Key Agreement with Physical Unclonable Functions: An Optimality Summary

no code implementations16 Dec 2020 Onur Günlü, Rafael F. Schaefer

A physical unclonable function (PUF) is a promising solution for local security in digital devices and this review gives the most relevant summary for information theorists, coding theorists, and signal processing community members who are interested in optimal PUF constructions.

Differential Privacy for Eye Tracking with Temporal Correlations

no code implementations20 Feb 2020 Efe Bozkir, Onur Günlü, Wolfgang Fuhl, Rafael F. Schaefer, Enkelejda Kasneci

New generation head-mounted displays, such as VR and AR glasses, are coming into the market with already integrated eye tracking and are expected to enable novel ways of human-computer interaction in numerous applications.
