Abstract
In this work, we propose a class of equational theories for bounded binary circuits that have the finite variant property. These theories could serve as a building block to specify cryptographic primitive implementations and automatically discover attacks as binary circuits in the symbolic model. We provide proofs of equivalence between this class of equational theories and Boolean logic up to circuit size 3 and we provide the variant complexities and performance benchmarks using Maude-NPA. This is the first result in this direction and follow-up research is needed to improve the scalability of the approach.
