Abstract

In this work we discuss results obtained from an application of the Hadamard transform to cryptanalysis, and in particular, we determine the probability to decipher different pseudo-random number generators used as components of stream ciphers. Also, we found a relationship between entropy and Hadamard’s values.

Keywords: pseudo-random generators, Hadamard transform, stream ciphers, entropy
