A Fully Digital True Random Number Generator With Entropy Source Based in Frequency Collapse

All cryptography systems have a True Random Number Generator (TRNG). In the process of validating, these are necessary for prototyping in Field Programmable Gate Array (FPGA). However, TRNG uses an entropy source based on non-deterministic effects challenging to replicate FPGA. This work shows problems and solutions implement frequency collapse multimodal Ring Oscillators (RO). The implemented FPGA pass all SP800-90B tests from National Institute Standards Technology (NIST) with good compared related works. passes NIST SP800-22 without post-processing stage.
