Electronics Letters, Volume 61, Issue 1, January/December 2025.ASCON has been selected by the National Institute of Standards and Technology (NIST) as the new authenticated cipher for lightweight environments. This paper analyses ASCON's hardware (HW) security through its HW implementation schemes, successful HW attacks and the proposed HW countermeasures against them, aiming to serve as a starting point for ...

Optimal quantitative cryptanalysis of permutation-only multimedia ciphers against plaintext attacks
, 2011 Recently, an image scrambling encryption algorithm of pixel bit based on chaos map was proposed. Considering the algorithm as a typical binary image scrambling/permutation algorithm exerting on plaintext of size $M\times (8N)$, this paper proposes a ...

IET Information Security, Volume 2025, Issue 1, 2025.Public‐key authenticated encryption with keyword search (PAEKS) is a novel cryptographic primitive to resist against keyword‐guessing attacks (KGAs) and preserve the privacy of keywords in both ciphertexts and trapdoors. Recently, a designated‐server PAEKS (dPAEKS) scheme was proposed to withstand KGAs.

A New Method for Constructing Integral‐Resistance Matrix for 5‐Round AES
IET Information Security, Volume 2025, Issue 1, 2025.A powerful theory for evaluating block ciphers against integral distinguishers was introduced by Hebborn et al. at ASIACRYPT 2021. To show the integral‐resistance property for a block cipher, their core idea is to construct a full‐rank integral‐resistance matrix. However, their method does not work practically for 5‐round AES due to the large S‐box and

Replication of ciphertext in cryptographic system
Journal of Applied Sciences and Environmental Management, 2018 Eavesdroppers are constantly trying to reveal encrypted messages sent within communication channels. The motive to illegally decrypt ciphertexts (encrypted messages) could be for economical, security or political reasons.

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 ...

IACR Transactions on Symmetric Cryptology, 2016 In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function evaluations.
