Cryptanalysis on Two Kinds of Number Theoretic Pseudo‐Random Generators Using Coppersmith Method
IET Information Security, Volume 2025, Issue 1, 2025.Pseudo‐random number generator (PRNG) is a type of algorithm that generates a sequence of random numbers using a mathematical formula, which is widely used in computer science, such as simulation, modeling applications, data encryption, et cetera. The efficiency and security of PRNG are closely related to its output bits at each iteration.

Algebraic Attacks against Some Arithmetization-Oriented Primitives
IACR Transactions on Symmetric Cryptology, 2022 Recent advanced Zero-Knowledge protocols, along with other high-level constructions such as Multi-Party Computations (MPC), have highlighted the need for a new type of symmetric primitives that are not optimized for speed on the usual platforms (desktop

Constructing Efficient Identity‐Based Signatures on Lattices
IET Information Security, Volume 2025, Issue 1, 2025.In this work, we explore the recent developments related to lattice‐based signature and preimage sampling, and specify a compact identity‐based signature (IBS) on an ideal lattice for practical use. Specifically, we first propose an ellipsoid version of the G + G signature scheme (Asiacrypt 2023) that achieves slightly better signature size and higher ...

Further Results of the Cryptographic Properties on the Butterfly Structures
, 2016 Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equal to 4 and algebraic degree is also very high when exponent $e=3$.

A Fast Search Method for 3‐Share Second‐Order Masking Schemes for Lightweight S‐Boxes
IET Information Security, Volume 2025, Issue 1, 2025.Masking schemes are widely adopted strategies for countering side‐channel analysis (SCA) attacks. The initial hardware masking strategy, threshold implementation (TI), provides robust security against glitches in hardware platforms. The minimum number of shares required for a TI scheme depends not only on the desired security order but also on the ...
