Gbps-magnitude high-speed real-time physical random number generation method and device

Abstract

The invention belongs to the technical field of integrated circuits, and particularly relates to a Gbps-magnitude high-speed real-time physical random number generation method and device, and the device comprises a physical entropy source module, an entropy extraction module, a post-processing circuit module and a gigabit transceiver module. The physical entropy source uses a 66-node autonomous Boolean network to generate a chaotic signal. A D trigger is used as an entropy extractor to extract the chaotic analog signal into a chaotic digital signal. The post-processing circuit is used for carrying out depolarization and decorrelation operation on the single-path chaotic digital signal, and finally the gigabit transceiver is used for carrying out serialization output to obtain a single-pathhigh-speed real-time physical random number. High-speed real-time physical random numbers can be generated in real time, integration and miniaturization of the high-speed physical random numbers areachieved, and the technical requirements of communication technology development are met.

Description

technical field [0001] The invention relates to the field of integrated circuits and cryptographic chips, in particular to a Gbps level high-speed, real-time physical random number generation method and device, which are suitable for the field of secure communication. Background technique [0002] Physical random number generators are widely used in scientific computing, simulation and other fields. Due to the uncertainty and aperiodicity of the output, their role in the field of secure communication is particularly prominent. They are usually used for secret key generation, vector initialization and random fill values ​​and many other aspects. [0003] With the development of computer and communication technology, the throughput of communication data has reached the level of G bps or even T bps. Based on the "one-time pad" theory proposed by Shannon, the originator of information theory, in order to ensure the communication and security of such high-throughput data, it is ...

AI Technical Summary

Problems solved by technology

The physical random number generator implemented based on the above method is either limited by the low bandwidth of the entropy source and cannot achieve a high rate, or is limited by the huge volume and is difficult to adapt to the current development trend of device miniaturization and integration.
