Understanding RNG: Is Random Number Generation Truly Random?

Explore whether random number generation (RNG) is truly random or pseudorandom and discover its implications for security and algorithms.

49 views

RNG, or random number generation, is often not completely random. Most RNGs use algorithms that generate pseudorandom numbers based on initial values known as seeds. This means that if you know the seed, you could predict the sequence. For applications requiring higher security or true randomness, hardware RNGs that derive randomness from physical processes are used.

FAQs & Answers

  1. What is RNG and how does it work? RNG stands for random number generation and it works by using algorithms or physical processes to produce sequences of numbers.
  2. Are pseudorandom numbers secure? Pseudorandom numbers can be predictable if the seed value is known, which is why hardware RNGs are preferred for secure applications.
  3. What are hardware random number generators? Hardware RNGs generate randomness from physical processes, such as electronic noise, and are used for applications needing true randomness.
  4. Why is randomness important in algorithms? Randomness is crucial in algorithms for ensuring unpredictability in simulations, cryptography, and other computational tasks.
