Logical cryptanalysis
Witryna30 wrz 2024 · The fact of the matter is that cryptology encompasses both cryptography and cryptanalysis, which is about making and breaking the codes, respectively. Therefore, cryptology, which uses both methods, is basically a mathematical study of codes, cyphers and algorithms. That being said, the earliest known use of … WitrynaWe offer the new approach to a logical cryptanalysis.

Witryna15 sie 2003 · Logical cryptanalysis has been introduced by Massacci and Marraro as a general framework for encoding properties of crypto-algorithms into SAT problems, … WitrynaWe offer the new approach to a logical cryptanalysis. If the algebraic attack tries to use the classic methods of solution of the systems of non-linear equations, our method uses the tools of discrete mathematics. The characteristic feature of our approach is simplicity. In the examined cryptosystem, the input vector is subjected to transfor-

This paper deals with this concept applied to cryptographic hash functions. We first present the logical cryptanalysis principle, and provide details about our encoding …
Witryna21 mar 2024 · Logical cryptanalysis, first introduced by Massacci in 2000, is a viable alternative to common algebraic cryptanalysis techniques over boolean fields. With XOR operations being at the core of many cryptographic problems, recent research in this area has focused on handling XOR clauses efficiently. In this paper, we investigate solving …
