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.

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.

Yoyo Cryptanalysis Against Reduced‐Round L‐Feistel Structure for Recovering the Secret Components
IET Information Security, Volume 2025, Issue 1, 2025.L‐Feistel structure is a new iterative block cipher structure and unifies the Feistel structure and the Lai–Massey structure while maintaining the similarity of encryption and decryption. In this study, we present the first yoyo cryptanalysis against the L‐Feistel structure to evaluate the security under structural attack and give the method to recover

Security analysis of an encryption scheme based on nonpositional polynomial notations
Open Engineering, 2016 The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (

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

Subspace Trail Cryptanalysis and its Applications to AES
IACR Transactions on Symmetric Cryptology, 2017 We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...
