摘　　要：随机数作为网络空间安全的基础技术历来受到相关领域研究人员的重视。针对日益广泛的真随机数应用需求,在分析国内外各种真随机数生成方法的基础上,基于物理噪声源芯片和内含微处理器的USB接口芯片构建一个真随机数生成平台。给出平台的总体设计框图,详细分析了平台核心硬件的配置电路设计和固件程序以及上位机软件设计。该平台具有结构简单、实现方便、可扩展性强等特点,通过该平台的构建一方面可以方便快捷地获取大量真随机数,另一方面将该平台应用于课程教学实践,对于相关专业学生学习了解真随机数的典型产生方法具有重要意义。As the foundation technology of the network security related fields,the random numbers are paid more attention. In view of the increasingly application requirements of the true random numbers,based on analysis of the generating methods of true random numbers,a true random number generation platform based on a physical noise source chip and a USB interface chip with a microprocessor embedded is constructed,the overall block diagram of the platform is proposed,the configuration circuit of the core hardware is designed,and the design of the firmware and the host computer software are analyzed in detail. The platform has some advantages such as a simple structure,convenient implementation and good expansibility. A large number of true random numbers can be acquired from the constructed platform fast and conveniently,and it can be applied in teaching practice,so that the students of related subjects can learn about the typical method of the true random number generator.
