Novel Optical Fast Random Number Generators Based on Integer Domain Chaotic Iterations

摘要

For cryptography and secure communications, it is very prerequisite that the random number generator (RNG) is based on non-deterministic physical mechanisms, extremely fast generator and robustness to noise are required. In this work, we present novel fast optoelectronic architecture RNGs based on integer domain chaotic iteration (IDCI), with a chaotic semiconductor laser, having time-delayed self-feedback. The solution stems from some well-defined discrete chaotic iterations that satisfy the reputed Devaney's definition of chaos, namely the integer domain chaotic iterations technique, improve the statistical properties of this RNG. Using standard criteria named NIST and DieHARD (famous batteries of tests), the randomness of the output sequences is verified.
