Secrecy in the American Revolution
, 2019 This paper analyzes how the use of various cryptographic and cryptanalytic techniques affected the American Revolution. By examining specific instances of and each country\u27s general approaches to cryptography and cryptanalysis, it is determined that ...

, 2016 Standard differential cryptanalysis uses statistical dependencies between the difference of two plaintexts and the difference of the respective two ciphertexts to attack a cipher. Here we introduce polytopic cryptanalysis which considers interdependencies between larger sets of texts as they traverse through the cipher. We prove that the methodology of

Influence of Non-Linearity on Selected Cryptographic Criteria of 8x8 S-Boxes
Acta Informatica Pragensia, 2017 The article defines standard criteria used to characterize the cryptographic quality of the S box: regularity, non linearity, autocorrelation, avalanche and immunity against differential cryptanalysis.

A note on some algebraic trapdoors for block ciphers
, 2018 We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al.

Cryptanalysis of 2R− Schemes [PDF]
, 2006 In this paper, we study the security of 2R− schemes [17,18], which are the “minus variant” of two-round schemes. This variant consists in removing some of the n polynomials of the public key, and permits to thwart an attack described at Crypto'99 [25] against two-round schemes.

Related-Key Differential Cryptanalysis of the Reduced-Round Block Cipher GIFT
IEEE Access, 2019 GIFT is a lightweight block cipher that was proposed by Banik et al. at CHES 2017, which is said to be a direct improvement over PRESENT since “that provides a much increased efficiency in all domains (smaller and faster)” and improves the security ...

Analysis of the cryptographic strength of the SHA-256 hash function using the SAT approach
Научно-технический вестник информационных технологий, механики и оптикиCryptographic hash functions play a significant role in modern information security systems by ensuring data integrity and enabling efficient data compression. One of the most important and widely used cryptographic hash functions is SHA-256 that belongs

Cryptanalysis of Yang-Wang-Chang's Password Authentication Scheme with Smart Cards
, 2008 In 2005, Yang, Wang, and Chang proposed an improved timestamp-based password authentication scheme in an attempt to overcome the flaws of Yang-Shieh_s legendary timestamp-based remote authentication scheme using smart cards.
