WebJul 13, 2024 · July 13, 2024 Pseudo Random Number Generator (PRNG) Software-generated random numbers only are pseudorandom. They are not truly random because the computer uses an algorithm based on a distribution, and are not secure because they rely on deterministic, predictable algorithms. WebThe NIST test suite is the most popular test suite for evaluating the randomness of pseudo-random sequences. These tests may be useful as a first step in determining whether a generator is suitable for a particular cryptographic application. Table 8 shows the NIST SP800 test results of the proposed PRNG. graphical shapes png
