Zigzag map: A variability-aware discrete-time chaotic-map truly random number generator
نویسندگان
چکیده
In this letter, we present a circuit implementation for the discrete-time zigzag map, which exhibits high speed, low power consumption, and above all resilience to process variations. Circuit parameter variations result in alteration of the chaotic map parameters, such as the slope and the location of the breakpoints in the map, which in turn degrade the randomness of the generated bit sequence or even cause saturation problem when the map is used in a truly random number generator (TRNG). Due to the resilience of the presented circuit implementation to process variations, a truly random sequence is obtained that passes all the TRNG statistical test suites, after very simple postprocessing of the output bit sequence.

The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
