Refined Probability of Differential Characteristics Including Dependency Between Multiple Rounds
differential cryptanalysis independent S-box fixed key
2017/5/31
The current paper studies the probability of differential characteristics for an unkeyed (or with a fixed key) construction. Most notably, it focuses on the gap between two probabilities of differenti...
Constructing Mixed-integer Programming Models whose Feasible Region is Exactly the Set of All Valid Differential Characteristics of SIMON
Automatic cryptanalysis Related-key differential attack Mixed-integer Linear Programming
2016/1/4
In IACR ePrint 2014/747, a method for constructing mixed-integer linear programming (MILP) models whose feasible regions are exactly the sets of all possible differential (or linear) characteristics f...
Towards Finding Optimal Differential Characteristics for ARX: Application to Salsa20
Evaluation Tool SAT solver
2014/3/12
An increasing number of cryptographic primitives are built using the ARX operations: addition modulo $2^n$, bit rotation and XOR. Because of their very fast performance in software, ARX ciphers are be...
The Best Differential Characteristics and Subtleties of the Biham-Shamir Attacks on DES
Block ciphers Feistel schemes DES S-box design
2009/2/16
In about every book about cryptography, we learn that the
plaintext complexity of differential cryptanalysis on DES is 247, as reported
by Biham and Shamir in [2]. Yet few people realise that in a
