A Novel Pseudo-random Bit Generator Based on Some Transcendental Chaotic Systems

Chaotic maps have attracted great interest for its special use in secure communication systems. It is proved that for some chaotic maps defined by we can find an analytical solution, so systems can leads to predictability. In this letter, we propose a new kind of chaotic map based on transcendental equations, which appear completely different deterministic random behavior with the known chaotic maps and have a kind of more complicated dynamical behavior. We study the effectiveness of the practical application of such systems for generating sequences of pseudorandom numbers and we investigate the properties of the obtained data to confirm them for cryptographic purpose.
