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

Single-Trace Attacks on Keccak [PDF]
Iacr Transactions on Cryptographic Hardware and Embedded Systems, 2020 Since its selection as the winner of the SHA-3 competition, Keccak, with all its variants, has found a large number of applications. It is, for instance, a common building block in schemes submitted to NIST’s post-quantum cryptography project. In many of

Preimage Attacks on Reduced-Round Keccak Hash Functions by Solving Algebraic Systems
IET Information Security, 2023 In this paper, improved preimage attacks are presented on 3‐round Keccak‐256 and Keccak‐512 and 4‐round Keccak‐256 based on algebraic methods. The authors propose some new properties about the components of Keccak permutation, reconsider the existing ...

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

Revisiting Keccak and Dilithium Implementations on ARMv7-M
Iacr Transactions on Cryptographic Hardware and Embedded SystemsKeccak is widely used in lattice-based cryptography (LBC) and its impact to the overall running time in LBC scheme can be predominant on platforms lacking dedicated SHA-3 instructions. This holds true on embedded devices for Kyber and Dilithium, two LBC

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

Improved Preimage Attacks on 4-Round Keccak-224/256
IACR Transactions on Symmetric Cryptology, 2021 This paper provides an improved preimage attack method on standard 4-round Keccak-224/256. The method is based on the work pioneered by Li and Sun, who design a linear structure of 2-round Keccak-224/256 with 194 degrees of freedom left.

Preimage Attacks on the Round-reduced Keccak with Cross-linear Structures
IACR Transactions on Symmetric Cryptology, 2017 In this paper, based on the work pioneered by Aumasson and Meier, Dinur et al., and Guo et al., we construct some new delicate structures from the roundreduced versions of Keccakhash function family. The new constructed structures are called cross-linear
