Decorrelation: A Theory for Block Cipher Security [PDF]
, 2018 Pseudorandomness is a classical model for the security of block ciphers. In this paper we propose convenient tools in order to study it in connection with the Shannon Theory, the Carter-Wegman universal hash functions paradigm, and the Luby-Rackoff ...

Feistel Ciphers with L 2-Decorrelation [PDF]
, 1999 Recently, we showed how to strengthen block ciphers by decorrelation techniques. In particular, we proposed two practical block ciphers, one based on the GF(2n)-arithmetics, the other based on the x mod p mod 2n primitive with a prime p = 2n(1 + δ). In this paper we show how to achieve similar decorrelation with a prime p = 2n(1 - δ).

Interactions Between Diurnal Warm Layers and Surface‐Layer Fronts
Journal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.Abstract Previous studies have highlighted the individual importance of diurnal warm layers (DWLs) and surface‐layer fronts within the surface boundary layer (SBL) in regulating energy, momentum, and gas exchange between the atmosphere and the ocean. This study investigates the interactions between DWLs and surface‐layer fronts using field observations

Links between Quantum Distinguishers Based on Simon’s Algorithm and Truncated Differentials
IACR Transactions on Symmetric CryptologyIn this paper, we study the quantum security of block ciphers based on Simon’s period-finding quantum algorithm. We explored the relations between periodic functions and truncated differentials. The basic observation is that truncated differentials with
