(Not Surprising) Attacks on Recent Pairing‐Free Attribute‐Based Encryption Schemes
IET Information Security, Volume 2026, Issue 1, 2026.The fact that designing secure and efficient identity or attribute‐based encryption (ABE) schemes requires the use of specific algebraic tools like bilinear pairings or lattices is well known in the cryptographic community. However, some journals whose main topics are not cryptographic still publish papers proposing, for instance, ABE schemes in ...

Enhancing Differential-Linear Cryptanalysis [PDF]
, 2002 Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linear relations. In 1994, Langford and Hellman showed that both kinds of analysis can be combined together by a technique called differential-linear cryptanalysis, in which the ...

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF
IET Information Security, Volume 2026, Issue 1, 2026.The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field
Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.

On Matsui's linear cryptanalysis [PDF]
, 1995 In [9] Matsui introduced a new method of cryptanalysis, called Linear Cryptanalysis. This method was used to attack DES using 247 known plaintexts. In this paper we formalize this method and show that although in the details level this method is quite different from differential cryptanalysis, in the structural level they are very similar. For example,

A Secure and Robust Blockchain‐Based Medical Image Encryption Approach Using Lorenz Chaotic System
Journal of Sensors, Volume 2026, Issue 1, 2026.Keeping medical images confidential while transmitting is crucial, especially in an open networking environment. One effective approach is blockchain‐based encryption, which provides strong security for sensitive healthcare data. To ensure the greatest levels of medical data integrity and authenticity, our proposed scheme employs a unique Lorenz ...

Linearity in decimation-based generators: an improved cryptanalysis on the shrinking generator
Open Mathematics, 2018 Decimation-based sequence generators are a class of non-linear cryptographic generators designed to be used in hardware implementations. An inherent characteristic of such generators is that their output sequences are interleaved sequences.
