High-speed random number generating system based on chaos network

Abstract

The invention provides a high-speed random number generating system based on a chaos network. The high-speed random number generating system comprises the digital chaos network, one or more random code registers connected with the digital chaos network, and one or more data interfaces connected with the random code registers. The parallel algorithm technology and the assembly line technology are adopted for the digital chaos network, random codes or pseudo-random codes generated among nodes of the digital chaos network are coupled, the frequency spectrum of the chaos network is broadened, and therefore the number of random codes of each digital variable of the digital chaos network is increased, and low-order random codes are obtained. The random codes of all the variables or a part of the variables of the digital chaos network are taken out and encoded according to a random arraying method to form high-speed random number sequence codes, and the high-speed random number sequence codes are outputted through the random code registers connected with the digital chaos network and through the data interfaces connected with the random code registers. By means of the random number generating system, random codes at the speed of more than Tbits/s can be generated, and the high-speed random number generating system can be used for encryption of high-speed information and used for decryption of information through chaotic synchronization.

technical field [0001] The invention relates to the technical field of electronics, in particular to a high-speed random number generation system based on a complex digital chaotic network. Background technique: [0002] In recent years, high-speed random number generation based on chaotic systems has aroused great international research interest. People use chaotic laser, chaotic superlattice and chaotic logic gate network to produce 10 1-2 Gbit / s high-speed random number. However, the following problems exist in the research so far: [0003] (1) The chaotic signals used to generate high-speed random numbers are mostly generated by small chaotic systems, such as single lasers, double lasers, and weakly coupled superlattice laser chaotic systems, which limits the increase in the rate of random numbers. [0004] (2) In order to increase the rate of random number generation, high-speed data acquisition and post-data processing (such as high-order differential operations, et...

Problems solved by technology

[0003] (1) The chaotic signals used to generate high-speed random numbers are mostly generated by small chaotic systems, such as single lasers, double lasers and weakly coupled superlattice laser chaotic systems, which limits the increase in the rate of random numbers

[0004] (2) In order to increase the rate of random number generation, high-speed data acquisition and post-data processing (such as high-order differential operations, etc.) technology must be adopted, which will greatly increase system cost and system complexity, and bring inconvenience to actual use

[0005] (3) Digitizing the chaotic signal generated by the simulated chaotic system will inevitably cause noise to be mixed into the random number system, which brings difficulties in deciphering the high-speed random number confidential communication

[0006] (4) There is no report on the digitization of complex electronic networks described by differential equations to generate high-speed random numbers
