ADD-based Spectral Analysis of Probing Security

In this paper, we introduce a novel exact verification methodology for non-interference properties of cryptographic circuits. The methodology exploits the Algebraic Decision Diagram representation of the Walsh spectrum to overcome the potential slow down associated with its exact verification against non-interference constraints. Benchmarked against a standard set of use cases, the methodology speeds-up 1.88x the median verification time over the existing state-of-the art tools for exact verification.
