New Collision Attacks on Round-Reduced Keccak

2017
In this paper, we focus on collision attacks against Keccak hash function family and some of its variants. Following the framework developed by Dinur et al. at FSE 2012 where 4-round collisions were found by combining 3-round differential trails and 1-round connectors, we extend the connectors one round further hence achieve collision attacks for up to

Efficient Hybrid Random Number Generator Based on Keccak

2018 International Conference on Artificial Intelligence and Data Processing (IDAP), 2018
Random numbers are used in many areas such as cryptographic applications, statistics and game theory. These numbers are the most important part of these applications. There is a need for secure random numbers to guarantee the safety of these systems. In this study, a hybrid random number generator was designed to produce real random numbers that are ...

Анализ алгоритма хэширования Keccak

Безопасность является важнейшей характеристикой современных ИТ. Многие решения проблемы основаны на использовании хэш-преобразований. В докладе анализируется алгоритм Keccak, который генерирует хэши различных длин: 224, 256,384 и 512. Следует отметить, что Keccak является криптографически стойкой хэш-функцией, что означает, что для любой длины хэша ...
