Helper-Assisted Coding for Gaussian Wiretap Channels: Deep Learning Meets PhySec
Vidhi Rana, Remi A. Chou, Taejoon Kim
Consider the Gaussian wiretap channel, where a transmitter wishes to send a confidential message to a legitimate receiver in the presence of an eavesdropper. It is well known that…
Multi-Layer Secret Sharing for Cross-Layer Attack Defense in 5G Networks: a COTS UE Demonstration
Wai Ming Chan, Remi Chou, Taejoon Kim
This demo presents the first implementation of multi-layer secret sharing on commercial-off-the-shelf (COTS) 5G user equipment (UE), operating without infrastructure modifications…
Two-Dimensional XOR-Based Secret Sharing for Layered Multipath Communication
Wai Ming Chan, Remi Chou, Taejoon Kim
This paper introduces the first two-dimensional XOR-based secret sharing scheme for layered multipath communication networks. We present a construction that guarantees successful m…
Stabilization of Perturbed Loss Function: Differential Privacy without Gradient Noise
Salman Habib, Remi Chou, Taejoon Kim
We propose SPOF (Stabilization of Perturbed Loss Function), a differentially private training mechanism intended for multi-user local differential privacy (LDP). SPOF perturbs a st…
Sequential Interval Passing for Compressed Sensing
Salman Habib, Remi Chou, Taejoon Kim
The reconstruction of sparse signals from a limited set of measurements poses a significant challenge as it necessitates a solution to an underdetermined system of linear equations…
