Symmetric key cryptography, Asymmetric key cryptography, Hash function are the three categories of cryptography. Block cipher belongs to symmetric key cryptography. An encryption algorithm that ...

I did my project on how the Advanced Encryption Standard(AES) S-box is generated. The AES S-box is a component of the AES round function, which is essentially a lookup table, that takes an XOR between ...

Abstract: This paper studies the advanced methodologies of differential cryptanalysis with a particular emphasis on higher-order differentials and higher-order differential-linear cryptanalysis, along ...

Abstract: Linear attack is primarily introduced for DES encryption system by Matsui. This particular cryptanalysis was based on linear approximation of nonlinear S-boxes within the algorithm. This ...

ABSTRACT: 4-bit linear relations play an important role in cryptanalysis of 4-bit crypto S-boxes. 4-bit finite differences have also been a major part of cryptanalysis of 4-bit S-boxes. Existence of ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

SPARX is a family of ARX-based block ciphers designed according to the long-trail strategy, which has 32-bit ARX-based SBoxes and has provable bounds against single-differential and single-linear ...
