Efficient Detection and Quantification of Timing Leaks with Neural Networks

no code implementations23 Jul 2019 Saeid Tizpaz-Niari, Pavol Cerny, Sriram Sankaranarayanan, Ashutosh Trivedi

As demonstrated in our experiments, both of these tasks are feasible in practice --- making the approach a significant improvement over the state-of-the-art side channel detectors and quantifiers.

Quantitative Mitigation of Timing Side Channels

no code implementations21 Jun 2019 Saeid Tizpaz-Niari, Pavol Cerny, Ashutosh Trivedi

In contrast to the existing mitigation approaches, we show that in the functional-observation threat model, SCHMIT is scalable and able to maximize confidentiality under the performance overhead bound.

Data-Driven Debugging for Functional Side Channels

no code implementations30 Aug 2018 Saeid Tizpaz-Niari, Pavol Cerny, Ashutosh Trivedi

On the realistic programs, we show the scalability of FUCHSIA in analyzing functional side channels in Java programs with thousands of methods.

Differential Performance Debugging with Discriminant Regression Trees

no code implementations11 Nov 2017 Saeid Tizpaz-Niari, Pavol Cerny, Bor-Yuh Evan Chang, Ashutosh Trivedi

We propose a data-driven technique based on discriminant regression tree (DRT) learning problem where the goal is to discriminate among different classes of inputs.

Discriminating Traces with Time

no code implementations23 Feb 2017 Saeid Tizpaz-Niari, Pavol Cerny, Bor-Yuh Evan Chang, Sriram Sankaranarayanan, Ashutosh Trivedi

What properties about the internals of a program explain the possible differences in its overall running time for different inputs?
