Towards Scaling Robustness Verification of Semantic Features via Proof Velocity

no code implementations29 Sep 2021 Anan Kabaha, Dana Drachsler Cohen

We focus on robustness to perturbations of semantic features and introduce the concept of proof guided by velocity to scale the analysis.

Towards Physical, Imperceptible Adversarial Attacks via Adversarial Programs

no code implementations29 Sep 2021 Itai Mesery, Dana Drachsler Cohen

We leverage ideas from program synthesis and numerical optimization to search in this large, discrete space and obtain attacks that are competitive with the C&W attack but have at least 3x and up to 10x fewer perturbed pixels.

NETWORK ROBUSTNESS TO PCA PERTURBATIONS

no code implementations1 Jan 2021 Anan Kabaha, Dana Drachsler Cohen

In this work, we take a new approach and study the robustness of networks to the inputs' semantic features.

Securify: Practical Security Analysis of Smart Contracts

3 code implementations4 Jun 2018 Petar Tsankov, Andrei Dan, Dana Drachsler Cohen, Arthur Gervais, Florian Buenzli, Martin Vechev

To address this problem, we present Securify, a security analyzer for Ethereum smart contracts that is scalable, fully automated, and able to prove contract behaviors as safe/unsafe with respect to a given property.
