말뭉치

  1. A better solution is to use hardware random number generation.[1]
  2. “This is a marvelous step” toward more efficient random number generation, says Rajarshi Roy, a physicist at the University of Maryland in College Park who was not involved in the work.[2]
  3. Generator class is used in cases where you want each RNG call to produce different results.[3]
  4. The implementation selects the initial seed to the random number generation algorithm; it cannot be chosen or reset by the user.[4]
  5. Security can be established only if an RNG satisfies two conditions.[5]
  6. Given access to a specified source of randomness, the RNG produces samples from a desired target probability distribution.[5]
  7. The thermodynamics of generators enables direct bounds on the required physical resources, specifically on heat dissipation and work consumption during the operation of several classes of RNG methods.[5]
  8. For example, a RNG which relies on mouse movements or keyboard key presses would stop working once the user stops interacting with the mouse or the keyboard.[6]
  9. The bytes received from the entropy sources (RNG) are stored there.[6]
  10. Red Hat Enterprise Linux 7 includes virtio-rng, a virtual hardware random number generator device that can provide the guest with fresh entropy on request.[6]
  11. On the host physical machine, the hardware RNG interface creates a chardev at /dev/hwrng , which can be opened and then read to fetch entropy from the host physical machine.[6]
  12. For example, the Fortuna RNG has a trivial state transition function (it just increments a counter), but uses a cryptographic block cypher as the output function.[7]
  13. PCG's Output Function PCG uses a new technique called permutation functions on tuples to produce output that is much more random than the RNG's internal state.[7]
  14. When you seed the RNG, you are giving it an equivalent to a starting point.[8]
  15. Several different classes of pseudo-random number generation algorithms are implemented as templates that can be customized.[9]
  16. This study presents the true random number generation from bioelectrical signals like EEG, EMG, and EOG and physical signals, such as blood volume pulse, GSR (Galvanic Skin Response), and respiration.[10]
  17. The signals used in the random number generation were taken from BNCIHORIZON2020 databases.[10]
  18. Random number generation was performed from fifteen different signals (four from EEG, EMG, and EOG and one from respiration, GSR, and blood volume pulse datasets).[10]
  19. Hu et al. performed real random number generation by observing mouse movements of computer users.[10]
  20. Random number generation in Julia uses the Mersenne Twister library via MersenneTwister objects.[11]
  21. Julia has a global RNG, which is used by default.[11]
  22. Other RNG types can be plugged in by inheriting the AbstractRNG type; they can then be used to have multiple streams of random numbers.[11]
  23. Besides MersenneTwister , Julia also provides the RandomDevice RNG type, which is a wrapper over the OS provided entropy.[11]
  24. The package randtoolbox provides R func- tions for pseudo and quasi random number generations, as well as statistical tests to quantify the quality of generated random numbers.[12]
  25. In this section, we present rst the pseudo random number generation and second the quasi random number generation.[12]
  26. Pseudo random number generation aims to seem random whereas quasi random number generation aims to be determin- istic but well equidistributed.[12]
  27. randomness/. 3For true random number generation on R, use the random package of Eddelbuettel (2007).[12]
