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 ...

Secure and Fast Hashing Algorithm with Multiple Security Levels
Journal of Software, 2009 We propose a new secure and fast hashing algorithm with multiple security levels (SFHA-MSL). It is based on the generic 3C (3 compressions) construction and the 3C-X (3C XOR) hash function which is the simplest and efficient variant of the generic 3C hash function and it is the simplest modification to the Merkle-Damgard (M-D) iterated construction ...

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

A Large-Scale Secure Image Retrieval Method in Cloud Environment
IEEE Access, 2019 With the rapid development of cloud computing technology, more and more users choose to outsource image data to clouds. To protect data's confidentiality, images need to be encrypted before being outsourced to clouds, but this brings difficulties to some

Regular and almost universal hashing: an efficient implementation [PDF]
Software: Practice and Experience 47 (10), 2017, 2016 Random hashing can provide guarantees regarding the performance of data structures such as hash tables---even in an adversarial setting. Many existing families of hash functions are universal: given two data objects, the probability that they have the same hash value is low given that we pick hash functions at random.

DeepCatra: Learning flow‐ and graph‐based behaviours for Android malware detection
IET Information Security, Volume 17, Issue 1, Page 118-130, January 2023., 2023 Abstract As Android malware grows and evolves, deep learning has been introduced into malware detection, resulting in great effectiveness. Recent work is considering hybrid models and multi‐view learning. However, they use only simple features, limiting the accuracy of these approaches in practice.

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.
