摘要
本文对已有的几类真随机数发生器进行研究,分析了它们的优缺点。设计了一种基于Chua混沌电路的真随机数发生器并进行理论分析,利用Multisim软件进行电路仿真,最后实现了硬件电路的真随机数发生器。使用NIST随机性测试标准对产生的随机序列进行了随机性统计测试。测试结果验证了产生的随机序列具有良好的均匀性,随机性,不可预测性和不可重复性,可以广泛应用于数据加密等信息安全领域。
The paper explores several categories for existing true random number generators and analyzes their strengths and weaknesses. A true random number generator is designed based on Chua chaotic circuit and make theoretical analysis. Using Multisim software to simulate circuit and finally implementing it in hardware,for generated random sequences we do statistical tests of randomness on the NIST randomness testing standard. Test results show the random sequence generated with good uniformity,randomness,unpredictability and non-repeatability,and can be widely applied in the field of information security and data encryption.
