Single-Trace Attacks on Keccak [PDF]
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

Algebraic Collision Attacks on Keccak
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

A High-Entropy True Random Number Generator with Keccak Conditioning for FPGA. [PDF]
Sensors (Basel)Any cryptographic system strongly relies on randomness to ensure robust encryption and masking methods. True Random Number Generators play a fundamental role in this context. The National Institute of Standards and Technology (NIST) and the Bundesamt für

Low-Latency Keccak at any Arbitrary Order
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

Practical Preimage Attacks on 3-Round Keccak-256 and 4-Round Keccak[r=640, c=160]
IACR Transactions on Symmetric CryptologyRecently, linear structures and algebraic attacks have been widely used in preimage attacks on round-reduced Keccak. Inherited by pioneers’ work, we make some improvements for 3-round Keccak-256 and 4-round Keccak[r=640, c=160].

Revisiting Keccak and Dilithium Implementations on ARMv7-M
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
