Abstract

The present disclosure is related to a TRNG-type random bit generator using chaotic Boolean networks with applications for data encryption of information transmission systems. Using the chaotic behavior generated in an autonomous Boolean network for the manufacturing of a random bit generator of the TRNG-type to be used in the data encryption of information transmission systems. The application is not limitative, as it can be used in any application where randomness is required. The basic architecture that describes the fundamental operating principle of the invention comprises two chaotic Boolean oscillators that have different internal structures, two retention circuits and two output circuits. Using a mixed chaotic sample, two random output bits are obtained that do not require post processing, so their bit generation speed will only be limited by the technology used for its implementation. In addition, the proposed system is robust to the variations of the manufacturing process, as it does not depend on specific values to operate. Likewise, the output bits can be increased according to the number of bits required by a specific application by replicating the basic architecture, as many times as necessary; it is possible to obtain different bitrates per second. It is important to consider that the TRNG-type random bit generator system using Boolean chaotic oscillators can be physically implemented with different current electronic technologies. These technologies can be logic gates and programmable logic devices (PIC, DSP, FPGA, etc.) but not limited to future electronic technologies and not even limited to technologies in other knowledge areas, such as optics, quantum, photonics, etc. The performance of the data encryption system based on Boolean chaotic oscillators meets the requirements established by the cryptography rules and standards, specifically, the SP800-22 cryptography standard.
