A preimage attack on reduced GIMLI‐HASH with unbalanced squeezing phase

IET Information Security, Volume 17, Issue 1, Page 66-79, January 2023., 2023
Abstract In Conference on Cryptographic Hardware and Embedded System 2017, Bernstein et al. proposed GIMLI, a 384‐bit permutation with 24 rounds, which aims to provide high performance on various platforms. In 2019, the full‐round (24 rounds) GIMLI permutation was used as an underlying primitive for building AEAD GIMLI‐CIPHER and hash function GIMLI ...

T‐depth reduction method for efficient SHA‐256 quantum circuit construction

IET Information Security, Volume 17, Issue 1, Page 46-65, January 2023., 2023
Abstract To perform a quantum brute force attack on a cryptosystem based on Grover's algorithm, it is necessary to implement a quantum circuit of the cryptographic algorithm. Therefore, an efficient quantum circuit design of a given cryptographic algorithm is essential, especially in terms of quantum security analysis, and it is well known that T‐depth

Improved lattice‐based mix‐nets for electronic voting

IET Information Security, Volume 17, Issue 1, Page 18-34, January 2023., 2023
Abstract Mix‐networks were first proposed by Chaum in the late 1970s–early 1980s as a general tool for building anonymous communication systems. Classical mix‐net implementations rely on standard public key primitives (e.g., ElGamal encryption) that will become vulnerable when a sufficiently powerful quantum computer will be built.
