Abstract
Random numbers are indispensable resources for application in modern science and technology. Therefore a dedicated entropy source is essential particularly for cryptographic tasks and modern applications. In this work we experimentally demonstrated a scheme to generate random numbers by multiplexing eight tunnel diodes onto a single circuit. As a result the data rate of random number generation was significantly enhanced eightfold. In comparison to the original scheme that employed one diode this multiplexing scheme produced data with higher entropy. These data were then post-processed with the Toeplitz-hashing extractor yielding final outputs that achieved almost full entropy and passed the U.S. National Institute of Standards and Technology (NIST) Special Publication 800-90B validation. These data also passed the NIST Special Publication 800-22 statistical randomness examination and had no sign of patterns detected from an autocorrelation analysis. ? 2023 Author(s).
