Analysis of Unpredictable Cryptographic Pseudo-random Number Generator based on Non-linear Dynamic Chaotic System

A. Čitavičius, A. Jonavičius

Abstract


Most of pseudo-random number generators are unsuitable for cryptographic applications despite their statistical and correlation characteristics due to their backward and forward predictability. In this paper we presented an analysis of unpredictable cryptographic pseudo-random number generator based on non-linear dynamic chaotic system. We showed that we can get 48 bits from one float point and these bits generally passed NIST statistical test suite, therefore, we recommend to use this generator for cryptographic keys generation. Ill. 6, bibl. 6 (in English; summaries in English, Russian and Lithuanian).
