Abstract

The invention relates to a random number generating system and a random number generating method, wherein the random number generating system comprises super-lattice noise source, a power supply module, a quantifying and coding module and an output module; the super-lattice noise source generates a random noise simulating signal; the power supply module is electrically connected with the super-lattice noise source so as to provide offset voltage needed by the super-lattice noise source for processing chaotic oscillation spontaneously; the quantifying and coding module is electrically connected with the super-lattice noise source and the output module respectively and is used for quantifying and coding the random noise simulating signal so as to generate a random number code stream; and the output module outputs the random number code stream. The invention can obtain a random number sequence including true randomness and high quality; a generated speed can reach to more than Gbit / s; and the invention is applied to fields such as data encryption, key management, security protocol, digital signature, identity authentication and the like.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a random number generation system and a random number generation method. Background technique [0002] The random number generation system is an indispensable key component in the encryption system and various password security systems. Its working status directly affects the reliability and stability of the encryption system and various password security systems, and the quality of the generated random numbers It is related to the protection strength of cryptographic equipment for information. True randomness, high quality, and high speed are the three basic requirements for a random number generation system to generate high-quality random numbers. First, the random number generation system must have a high-quality noise source, that is, the signal is required to be truly random. Secondly, random numbers must meet the requirements of randomness, that is, they can pass various ...
