Abstract :
This paper presents results of studies on the implementation of pseudo-random bit generators based on a nonlinear dynamic chaotic system. Several solutions have been investigated, using different computing precision and various implementation of arithmetic operations. The results of the second level NIST tests for randomness of the proposed pseudo-random bit generators (PRBGs) are presented, that proved good cryptographic properties of the presented PRBGs. The generators described in this paper can be used for key generation in stream ciphers in secure, real-time transmission of digital signals, including audio-video applications.
