Revisiting the Extension of Matsui’s Algorithm 1 to Linear Hulls: Application to TinyJAMBU

Autor: Li, Muzhou, Mouha, Nicky, Sun, Ling, Wang, Meiqin

Publikováno v: IACR Transactions on Symmetric Cryptology; Volume 2022, Issue 2; 161-200

At EUROCRYPT ’93, Matsui introduced linear cryptanalysis. Both Matsui’s Algorithm 1 and 2 use a linear approximation involving certain state bits. Algorithm 2 requires partial encryptions or decryptions to obtain these state bits after guessing e

T₅: Hashing Five Inputs with Three Compression Calls

Autor: Dodis, Yevgeniy, Khovratovich, Dmitry, Mouha, Nicky, Nandi, Mridul

Given 2n-to-n compression functions h₁,h₂,h₃, we build a new 5n-to-n compression function T₅, using only 3 compression calls: T₅(m₁, m₂, m₃, m₄, m₅) : = h₃(h₁(m₁, m₂)⊕ m₅ , h₂(m₃, m₄)⊕ m₅) ⊕ m₅ We prove t

The domain of lightweight cryptography focuses on cryptographic algorithms for extremely constrained devices. It is very costly to avoid nonce reuse in such environments, because this requires either a hardware source of randomness, or non-volatile m

International audience; PRIMATEs are a family of permutation-based authenticated encryption algorithms for lightweight applications. They are currently under submission to the CAESAR competition. There are three PRIMATEs: the basic SpongeWrap-variant
