HIGH-SPEED RANDOM NUMBER GENERATOR

The utility model provides a high-speed random number generator. The high-speed random number generator comprises a master laser and a slave laser, light emitted by the main laser is divided into two parts through the optical fiber beam splitter, one part of light enters multi-path optical feedback and then returns to the main laser, and finally, the main laser enters chaotic state output under the disturbance of feedback light; and the other part of light serves as injection seed light of the slave laser and is injected into the slave laser through multi-path light, the slave laser also enters a chaotic state under the disturbance of the injection light, and finally, the chaotic light which is emitted by the laser and has enhanced bandwidth and no time delay characteristic serves as a chaotic entropy source of the random number generator. And after sampling quantization and post-processing optimization, a random number sequence meeting the NIST statistical test suite detection standard can be output. The high-speed random number generator provided by the utility model can provide a chaos entropy source with large bandwidth and fully eliminated time delay characteristics, is relatively easy to generate a high-speed and high-quality random number sequence, and is relatively simple in structure.
