WebThe Use of Random Numbers. A number of network security algorithms based on cryptography make use of random numbers. For example, Reciprocal authentication schemes, such as illustrated in Figures 7.9 and 7.11. In both of these key distribution scenarios, nonces are used for handshaking to prevent replay attacks.
WebApr 14, 2024 · The NIST SP 800-90 series provides guidance on the generation of high-quality random bits for cryptographic and non-cryptographic use. The security of a random number generator depends on the unpredictability of its outputs, which can be measured in terms of entropy.
