一种面向硬件实现的模数混合混沌真随机数发生器
Hardware-Oriented Modular Hybrid Chaotic True Random Number Generator
摘要
Abstract
In the field of information security,the application of random number generator is more and more extensive.The quasi-randomness and unpredictability of chaos can be used to design a random number generator with sound performance.Nevertheless,when the chaotic system is imple-mented in digital circuit,it will degrade and there will be serious security problems.In this study,a low-cost and high-efficiency true random number generator is designed and implemented by using an analog-digital hybrid chaos model.A two-stage comparator is used instead of ADC to achieve chaos quantization and obtain true random bits to reduce resource consumption.A hyperchaotic system is constructed using a comb-shaped chaos map that is easy to implement in hardware as the basic unit.The simulation of chaotic system uses the optical chaos equation to achieve a simple and higher rate.Using FPGA and FPAA,the joint hardware implementation of true random number generator is carried out.The overall circuit is simple,and the true random sequence generated with relatively low resource cost has high stability and excellent statistical performance.It has passed the NIST SP800 standard randomness test and the most stringent TestU01 test.The design is expected to be integrated into special chip and widely used in various fields of network security.关键词
