Digging Deeper: Operator Analysis for Optimizing Nonlinearity of Boolean Functions

no code implementations12 Feb 2023 Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

By observing the range of possible changes an operator can provide, as well as relative probabilities of specific transitions in the objective space, one can use this information to design a more effective combination of genetic operators.

On the Evolution of Boomerang Uniformity in Cryptographic S-boxes

no code implementations9 Dec 2022 Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Sihem Mesnager, Stjepan Picek

One example of such a property is called boomerang uniformity, which helps to be resilient against boomerang attacks.

Evolving Constructions for Balanced, Highly Nonlinear Boolean Functions

no code implementations17 Feb 2022 Claude Carlet, Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

Finding balanced, highly nonlinear Boolean functions is a difficult problem where it is not known what nonlinearity values are possible to be reached in general.

Evolutionary Construction of Perfectly Balanced Boolean Functions

no code implementations16 Feb 2022 Luca Mariot, Stjepan Picek, Domagoj Jakobovic, Marko Djurasevic, Alberto Leporati

Finding Boolean functions suitable for cryptographic primitives is a complex combinatorial optimization problem, since they must satisfy several properties to resist cryptanalytic attacks, and the space is very large, which grows super exponentially with the number of input variables.

Modeling Strong Physically Unclonable Functions with Metaheuristics

no code implementations16 Feb 2022 Carlos Coello Coello, Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

While there is no reason to doubt the performance of CMA-ES, the lack of comparison with different metaheuristics and results for the challenge-response pair-based attack leaves open questions if there are better-suited metaheuristics for the problem.
