We present recent results of our studies on the FPGA implementation of pseudo-random bit generators (PRBGs) based on a chaotic behavior of nonlinear systems. A number of different PRBG architectures have been considered, including logistic mapping, Hénon mapping, and frequency dependent negative resistor (FDNR). All versions of PRBGs have been(More)
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 pseudorandom bit(More)
Pseudo-random number generators (PRNGs) are one of the common parts of digital systems used in cryptography, diagnostics, simulation and in many other areas of modern science and technology. Here we present a novel architecture of the PRNG based on the chaotic nonlinear model and pipelined data processing. A significant enhancement in terms of output(More)
