  4. Pseudorandom noise - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_noise

    A pseudo-noise code (PN code) or pseudo-random-noise code (PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences , Gold codes , Kasami codes , and Barker codes .

    en.wikipedia.org/wiki/Pro_re_nata

    Generally abbreviated to "P.R.N." or "PRN", pro re nata refers to the administration of prescribed medication whose timing is left to the patient (in the case of patient-controlled analgesia), nurse, or caregiver, as opposed to medication that is taken according to a fixed (primarily daily) schedule (a.k.a. "scheduled dosage").

    C Alice = E(IV 1 xor P Alice) = E(IV 2 xor (IV 2 xor IV 1 xor P Alice)). [6] Depending on whether the IV for a cryptographic scheme must be random or only unique the scheme is either called randomized or stateful. While randomized schemes always require the IV chosen by a sender to be forwarded to receivers, stateful schemes allow sender and ...

    If you take every sequential group of three bit words in the PRBS3 sequence (wrapping around to the beginning for the last few three-bit words), you will find the following 7 word arrangements: " 101 1100" → 101 "1 011 100" → 011 "10 111 00" → 111 "101 110 0" → 110 "1011 100 " → 100 " 1 0111 00 " → 001 (requires wrap) " 10 1110 0 ...

  9. Pseudorandom number generator - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_number_generator

    A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), [1] is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers.
