Abstract

The invention is a method and device for generating high-speed random numbers, including two parts: an entropy source module and an entropy sampling module. The entropy source module is an autonomous Boolean network composed of digital logic gates, which consists of an exclusive NOR gate (XNOR) and N-1 exclusive OR gates (XOR), and the value of N is equal to 3n (n is a positive integer) , the entropy source module can generate a chaotic signal with a wide and flat spectrum. The entropy sampling module of the present invention is composed of D flip-flops, which samples and quantizes chaotic signals and then generates random number sequences. The random number sequence generated by the present invention can pass the random number industry test standard (NIST and Diehard statistical test), and has good random statistical properties. The invention is entirely composed of digital logic gates, the circuit structure is simple, and it is easy to be integrated and manufactured; it does not need post-processing algorithms or circuits necessary for conventional random number generators, and can greatly reduce its power consumption level. The invention can be widely used in information security fields such as secret communication, key distribution, data encryption and the like.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a method and device for generating high-speed random numbers. Background technique [0002] Random numbers have been used in scientific computing, digital communication, optical fiber sensing, radar ranging, identity authentication and other fields. Especially in the field of secure communication, with the rapid development of computer and network technology, how to ensure information security is extremely important. [0003] At present, many random number generators use computers combined with some deterministic mathematical algorithms (such as linear congruential methods, etc.) to quickly generate pseudo-random numbers, and pseudo-random numbers are periodic and can be predicted. These characteristics make pseudo-random numbers It is difficult for the server to ensure the security of encrypted information. [0004] Unlike pseudo-random numbers, physical random numbers are n...
