Abstract

This paper presents a novel chaotic-based pseudo-random number generator (PRNG) architecture, leveraging the Lorenz system, for secure fiber optic communication. We analyze a base model and an enhanced model, incorporating techniques like Euler integration, XOR operations, bifurcation analysis, and autocorrelation functions. The enhanced model, incorporating a feedback mechanism, exhibits superior performance in terms of output distribution, complexity, and randomness properties, as validated by NIST SP800-22 and NIST SP800-90B testings. Having passed all tests satisfactorily, we consider this improved model to be a cryptographically secure pseudo-random number generator (CSPRNG). This CSPRNG is adapted for fiber optic transmission, combining chaotic dynamics and fiber-optic technology for enhanced data security and reliability.
