Some Properties of Modular Addition
modular addition partitions differential cryptanalysis
2018/11/20
In this paper we study a problem which emerged during an attempt to apply a differential cryptanalysis method to the <<Magma>> algorithm. We obtained a general formula of distribution in the differenc...

In this article I analyze the function f(X) = A + X (mod 2a )
exclusive-or differential probability. 1 The result, regarding differential
cryptanalysis, is a better understanding of ciphers that use...
Cryptanalysis of Stream Ciphers Based on Arrays and Modular Addition
Cryptanalysis Ciphers Modular Addition
2008/9/16
In modern cryptography, stream ciphers are most useful in applications where
information needs to be encrypted/decrypted at high speed (e.g. high resolu-
tion streaming video data) or when low footp...
