Overconstrained character sums over finite abelian groups and decompositions of generalized bent, plateaued and landscape functions
Ayça ÃeÅmelioÄlu, Constanza Riera, Pantelimon StÄnicÄ
Generalized bent (gbent) functions from an -variable Boolean space to are central in cryptography and sequence design. Instead of the usual binary decompositi…

The revised boomerang connectivity tables and their connection to the Difference Distribution Table
Kirpa Garg, Sartaj Ul Hasan, Constanza Riera +1
It is well-known that functions over finite fields play a crucial role in designing substitution boxes (S-boxes) in modern block ciphers. In order to analyze the security of an S-b…

The second-order zero differential spectra of some functions over finite fields
Kirpa Garg, Sartaj Ul Hasan, Constanza Riera +1
It was shown by Boukerrou et al.~[IACR Trans. Symmetric Cryptol. 1 (2020), 331--362] that the -boomerang uniformity (which is the same as the second-order zero differential unif…
