Title:
ABBY: Automating the creation of fine-grained leakage models

Authors: Omid Bazangani, Alexandre Iooss, Ileana Buhan, Lejla Batina

Abstract:

Side-channel leakage simulators allow testing the resilience of cryptographic implementations to power side-channel attacks without a dedicated setup. The main challenge in their large-scale deployment is the limited support for target devices, a direct consequence of the effort required for reverse engineering microarchitecture implementations. We introduce ABBY, the first solution for the automated creation of fine-grained leakage models. The main innovation of ABBY is the training framework, which can automatically characterize the microarchitecture of the target device and is portable to other platforms. Evaluation of ABBY on real-world crypto implementations exhibits comparable performance to other state-of-the-art leakage simulators.
