Ao 基于振荡采样的真随机数发生器设计与实现

摘要

Based on the sampling clock oscillation theory,proposed a true random number generator structure. The use of mathematical models to ensure the noise source of reliable sources of noise,the use of the parallel output and controlled manner to ensure that the output rate of random numbers,reference designs online FIPS 140-2 random test module to avoid tampering suffered hardware problems.Through tests show that the production rate of a sequence of up to 33.5Mb/s,and has a high quality and can be used cryptographic chip products and other related fields.%基于时钟振荡采样原理，提出一种真随机数发生器结构。利用噪声源数学模型保证噪声源的可靠，利用并行输出及控制的方式确保随机数的输出速率，参考FIPS 140-2设计在线随机测试模块以避免遭受硬件篡改问题。通过测试表明，序列的产生速率可达33.5Mb/s，且具有较高的质量，可应用于密码芯片等相关领域产品中。
