Differential attacks are among the most important families of cryptanalysis against symmetric
primitives. Since their introduction in 1990, several improvements to the basic technique as …

SPEEDY is a family of ultra-lightweight block ciphers designed by Leander et al. at CHES
2021. There are three recommended variants denoted as SPEEDY-r-192 with r∈{5, 6, 7}. All …

In this paper, we present some new observations on the branch number and study concrete
differential analysis of SPEEDY. It is a new low-latency block cipher proposed at TCHES …

积分攻击是由Daemen 等人(doi: 10.1007/BFb0052343) 于1997 年提出的一种密码分析方法,
是继差分分析和线性分析之后最有效的密码分析方法之一. 作为2018 年全国密码算法设计竞赛 …

Integral attack is one of the most powerful cryptanalytic methods after differential and linear
cryptanalysis, which was presented by Daemen et al. in 1997 (doi: 10.1007/BFb0052343) …

This thesis in computer science focuses on the field of cryptography, in particular on
differential cryptanalysis. In this thesis, I present different cryptanalysis methods and …

En Criptografía, la cantidad de datos permitidos a cifrar con una sola llave en un algoritmo o
esquema de cifrado es conocida como tiempo de vida de la llave. Esta cantidad debe ser …

En este trabajo de diploma se presenta una propuesta de solución para desarrollar dos
aplicaciones móviles cartográficas, llamadas Encuestador y Notificador, que permitan …
