PURPOSE:To generate the pseudo random number having reproducibility being suitable especially for the use for a computer game by generating the random number by adding combination data of a prescribed address signal and a prescribed data signal. CONSTITUTION:In the case of generating random number ...
which uses a transition function of the formxn+1= (axn+c) modm. The maximum period of the generator ism(assuming the triple (a,c,m) has certain properties), but this means that in a 32-bit integer, the period can be at most 232, which is far too low. LCGs also have...

A hardware CSPRNG that is based on AES in CTR mode and is compliant with SP800-90A. In SP800-90A terminology, this is referred to as a DRBG (Deterministic Random Bit Generator), a term used throughout the remainder of this document. An ENRNG (Enhanced Non-deterministic Random Nu...

A random number generator, comprising: a first oscillator that outputs a first oscillating signal; a second oscillator that outputs a second oscillating signal, wherein the second oscillating signal has a much lower frequency than the first oscillating signal; and a sampling circuit that samples...

The well-known chaotic circuits are extremely simple, as they are composed only of an inductor and a capacitance diode, and thus it is easy to get the generator to work reliably. The output of the oscillators is discretized by a comparator, and these signals are mixed together using a D ...
1 Introduction Isogenies of elliptic curves are well-understood, at least from an algorithmic point of view, in theory and in practice. Given the Weierstrass equation of an elliptic curve E, and a generatorP of a finite subgroup of E, Vélu’s formulæ [54] allow us to write down ...
