Ultrametric integral cryptanalysis [PDF]

A systematic method to analyze divisibility properties is proposed. In integral cryptanalysis, divisibility properties interpolate between bits that sum to zero (divisibility by two) and saturated bits (divisibility by $2^{n - 1}$ for $2^n$ inputs ...

On relationship between differential/linear clustering effects and the number of active S-boxes in block ciphers

Cybersecurity
Differential cryptanalysis and linear cryptanalysis are the two best-known cryptanalysis techniques for symmetric-key primitives. Ensuring resistance to these attacks is critical for the security of block ciphers.

Towards Analysable Chaos-based Cryptosystems: Constructing Difference Distribution Tables for Chaotic Maps

Journal of Informatics and Web Engineering
Chaos-based cryptography has yet to achieve practical, real-world applications despite extensive research. A major challenge is the difficulty in analysing the security of these cryptosystems, which often appear ad hoc in design.

Cryptanalysis of an Enhanced Spatiotemporal Chaotic Image/Video Cryptosystem [PDF]

, 2011
This paper demonstrates that the enhanced cryptosystem is not secure against the following three different classical types of attacks: chosen plaintext, chosen ciphertext, and known plaintext.

Quantum Automated Tools for Finding Impossible Differentials

Mathematics
Due to the superiority of quantum computing, traditional cryptography is facing a severe threat. This makes the security evaluation of cryptographic systems in quantum attack models both significant and urgent.

Revisiting the shuffle of generalized Feistel structure

Cybersecurity
The Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

Multidimensional linear cryptanalysis [PDF]

, 2010
Linear cryptanalysis is an important tool for studying the security of symmetric ciphers. In 1993 Matsui proposed two algorithms, called Algorithm 1 and Algorithm 2, for recovering information about the secret key of a block cipher.

Comments on “A Conditional Privacy-Preserving Certificateless Aggregate Signature Scheme in the Standard Model for VANETs”

IEEE Access
In the above paper “A Conditional Privacy-Preserving Certificateless Aggregate Signature Scheme in the Standard Model for VANETs,” a pairing-based certificateless aggregate signature (CLAS) scheme was proposed.

Cryptanalysis of Ascon [PDF]

, 2017
We present a detailed security analysis of the CAESAR candidate Ascon. Amongst others, cube-like, differential and linear cryptanalysis are used to evaluate the security of Ascon.
