Cryptographically Strong Permutations from the Butterfly Structure
Kangquan Li, Chunlei Li, Tor Helleseth +1
In this paper, we present infinite families of permutations of with high nonlinearity and boomerang uniformity from generalized butterfly structures. Both…
Further study of -to- mappings over
Kangquan Li, Sihem Mesnager, Longjiang Qu
-to- mappings over finite fields play an important role in symmetric cryptography, in particular in the constructions of APN functions, bent functions, semi-bent functions an…
On a conjecture about a class of permutation quadrinomials
Kangquan Li, Longjiang Qu, Chao Li +1
Very recently, Tu et al. presented a sufficient condition about , see Theorem 1.1, such that is…
On the Differential-Linear Connectivity Table of Vectorial Boolean Functions
Anne Canteaut, Lukas Kölsch, Chao Li +4
Vectorial Boolean functions are crucial building-blocks in symmetric ciphers. Different known attacks on block ciphers have resulted in diverse cryptographic criteria for vectorial…

New Results about the Boomerang Uniformity of Permutation Polynomials
Kangquan Li, Longjiang Qu, Bing Sun +1
In EUROCRYPT 2018, Cid et al. \cite{BCT2018} introduced a new concept on the cryptographic property of S-boxes: Boomerang Connectivity Table (BCT for short) for evaluating the subt…
