【Abstract】 This article is focus on the design o f a high-performance pseudo-random number generator,DPFSR,which can be appli ed in the cryptography field.Based on the noise chip,the theory of LFSR and th e FPGA technology,the output rate of the pseudo-random number generator,DPFS R,can exceed one billion bits per second.Firstly,the idea of DPFSR is given a nd the security of DPFSR is discussed.Secondly,a model of DPFSR and the parame ters adopted in the model are presented as an example.Finally,the randomicity of the model is tested according to the special standard.更多还原
