Innovative Random Number Generation: From Lasers and Lava Lamps to Atmospheric Noise for Enhanced Cybersecurity

Random number generation is crucial for cybersecurity and encryption. * Pseudorandom Number Generators (PRNGs) use algorithms, while True Random Number Generators (TRNGs) use physical processes. * Lasers can generate random bits at over ten Gigabits per second, but require bias removal. * Random.org uses atmospheric noise variations to generate random numbers. * Lava lamps' patterns are converted into random data, named Lavarand. * Animals were used to randomly select numbers in lotteries. * Encryption algorithms use random numbers for unique session keys.
