A slightly slower period yet still new work on differential privacy and covert channels!
- Differentially Private Confidence Intervals for Empirical Risk Minimization
Addresses the question of computing confidence intervals in a private manner, using either DP or concentrated DP. Gives concrete examples and experiments using logistic regression and SVM.
- PowerHammer: Exfiltrating Data from Air-Gapped Computers through Power Lines
More work on leaking data from air-gapped computers through obscure side-channels, this time through power lines by varying the CPU utilization, achieving bit rates of 10-1000 bit/sec for different attacks.
