摘要

提出了一种基于可交换矩阵反馈环振荡器(SMFRO)的熵源真随机数发生器。SMFRO结构利用多重反馈机制产生可靠的混沌振荡。测试了在FPGA上采用不同资源配置实现的三种smro。它们都能通过混沌振荡和NIST测试。所提出的设计可以产生500MHz的随机比特，而无需额外的后处理。

A Novel High-speed FPGA-based True Random Number Generator Based on Chaotic Ring Oscillator

This paper presents a novel true random number generator with entropy source based on swappable matrix feedback ring oscillator (SMFRO). The proposed SMFRO structure utilizes multiple feedback mechanism to produce reliable chaotic oscillation. Three SMFROs implemented on FPGA with different resource configurations are tested. All of them can pass chaotic oscillation and NIST tests. Proposed design can generate random bits at 500MHz without extra post-processing.
