The Role of Random Number Generators in HSMs & Key …

WebPseudo-random number generators (PRNGs) are algorithms that can create long runs of numbers with good random properties but eventually the sequence repeats. Thus, the term ‘pseudo’ random number generators. The algorithms essentially generate numbers that, while not being truly random, are random enough for cryptographic applications.
