In theoretical computer science and cryptography, a pseudorandom generator (PRG) for a class of statistical tests is a deterministic procedure that maps a random seed to a longer pseudorandom string such that no statistical test in the class can distinguish between the output of the generator and the uniform distribution. The random seed itself is typically a short binary string drawn from the uniform distribution.

Property Value
dbo:abstract
  • En informatique théorique, un générateur pseudo-aléatoire (pour une classe de tests statistiques) est une procédure déterministique qui, donnée une chaîne aléatoire, en renvoie une plus longue de manière qu'aucun test de la classe correspondante puisse distinguer la chaîne retournée d'une chaîne aléatoire.

  • In theoretical computer science and cryptography, a pseudorandom generator (PRG) for a class of statistical tests is a deterministic procedure that maps a random seed to a longer pseudorandom string such that no statistical test in the class can distinguish between the output of the generator and the uniform distribution. The random seed itself is typically a short binary string drawn from the uniform distribution. Many different classes of statistical tests have been considered in the literature, among them the class of all Boolean circuits of a given size.It is not known whether good pseudorandom generators for this class exist, but it is known that their existence is in a certain sense equivalent to (unproven) circuit lower bounds in computational complexity theory.Hence the construction of pseudorandom generators for the class of Boolean circuits of a given size rests on currently unproven hardness assumptions.

  • 伪随机数生成器(pseudo random number generator,PRNG),又被称为确定性随机比特生成器(deterministic random bit generator,DRBG),是一个生成数字序列的算法,其特性近似于随机数序列的特性。伪随机数生成器生成的序列并不是真随机,因此它的每一个数完全由一个初始值决定,这个初始值被称为(seed,这个种子有时使用接近于真随机的硬件随机数生成器)。尽管接近于真随机的序列可以通过硬件随机数生成器生成,但伪随机数生成器因为其生成速度和可再现的优势,在实践中也很重要。 PRNG是仿真(例如,蒙特卡洛方法)、电子游戏(例如过程生成)以及密码学等应用的核心。加密应用程序要求不能从以前的输出中预测输出,而且更复杂的、不具有简单PRNGs线性特性的算法是必要的。 良好的统计特性,是PRNG的核心。通常,需要严格的数学分析来证明PRNG生成的序列足够接近真随机以满足预期用途。 (zh)
