Extending the quasidifferential framework: from fixed-key to expected differential probability Permalink
Published in IACR Transactions on Symmetric Cryptology, 2025
In this paper, we extend the quasidifferential framework from Beyne and Rijmen to the related-key setting. Furthermore, we also extend it to compute the EDP of a characteristic. We also propose some practical modeling of those extensions and apply them on SKINNY and the AES.
