Algebraic Collision Attacks on Keccak [PDF]
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we analyze the collision resistance of the two smallest versions of Keccak which have a width of 200 and 400 bits respectively. We show that algebraic and linearization techniques can serve collision cryptanalysis by using some interesting

Low-Latency Keccak at any Arbitrary Order [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2021 Correct application of masking on hardware implementation of cryptographic primitives necessitates the instantiation of registers in order to achieve the non-completeness (commonly said to stop the propagation of glitches). This sometimes leads to a high

Improved Preimage Attacks on 3-Round Keccak-224/256
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we provide an improved method on preimage attacks of standard 3-round Keccak-224/256. Our method is based on the work by Li and Sun. Their strategy is to find a 2-block preimage instead of a 1-block one by constructing the first and second
