On the Relationships between Different Methods for Degree Evaluation
2021
IACR Transactions on Symmetric Cryptology
In this paper, we compare several non-tight degree evaluation methods i.e., Boura and Canteaut's formula, Carlet's formula as well as Liu's numeric mapping and division property proposed by Todo, and hope to find the best one from these methodsfor practical applications. Specifically, for the substitution-permutation-network (SPN) ciphers, we first deeply explore the relationships between division property of an Sbox and its algebraic properties (e.g., the algebraic degree of its inverse).
