2014 IEEE Transactions on Circuits and Systems Part 1: Regular Papers  
As an illustration, such random bit sequences extracted from different entropy sources are investigated. Optoelectronic noise is used as a non deterministic entropy source.  ...  Electro-optic phase chaotic signal, as well as simulations of its deterministic model, are used as deterministic entropy sources. In all cases, the extracted bit sequence reveals excellent randomness.  ...  METHOD FOR RANDOM BIT SEQUENCE GENERATION FROM AN OPTOELECTRONIC SIGNAL In this section we describe the physical setup from which we expect to obtain a fast random bit sequence.  ...

Generating randomness: making the most out of disordering a false order into a real one

Yaron Ilan
2019 Journal of Translational Medicine  
Randomness is far from a disturbing disorder in nature. Rather, it underlies many processes and functions.  ...  This paper reviews methods of generating randomness in various fields. The potential use of these methods is also discussed.  ...  Physical broadband white chaos generated by optical heterodyning of two lasers was described as an entropy source to construct high-speed random bit generation with minimal postprocessing [70] .  ...

Encryption key distribution via chaos synchronization

Lars Keuninckx, Miguel C. Soriano, Ingo Fischer, Claudio R. Mirasso, Romain M. Nguimdo, Guy Van der Sande
2017 Scientific Reports  
Although derived from a deterministic process, the obtained bit series fulfill the randomness conditions as defined by the National Institute of Standards test suite.  ...  The concept is sufficiently generic to be implemented on either photonic, optoelectronic or electronic platforms.  ...  From the broadband chaos at the output of the sender module's responder, random bits can be generated by sampling the chaotic time evolution and by converting analog signals to digital.  ...
