Abstract: To solve the problem the known high quality random sequence generate scheme is slow and inefficient, we propose a new method which is called as Xiao’s Random Sequence Generate Scheme. It utilizes the point device as the noise signal source and has been applied for the Chinese patent of invention (CN200510018917.5). In addition, we analyze the performance, efficiency, security about the proposed schemes and test the generated sequence according to the standard of FIPS 140-2. The new scheme can get a batch of high-quality random number fitting to the requirements for the information security system, and it is quickly, security and efficient. Further more, we also build a truly random sequence generate system based the proposed scheme.

Key words: point devices, random s sequence, signal source, truly random number

摘要： 针对现有高质量随机序列生成方法的速度慢、效率低，无法满足信息安全系统需求等问题，提出了一种高效真随机序列生成方法。在此基础上设计了一个高效真随机序列生成系统，按照FIPS 140-2标准中的规定对由该系统产生的随机序列的质量进行了测试和分析。说明该方法能快速产生具有高质量的、满足信息安全系统标准的高强度安全随机序列，可以广泛应用于各种信息安全系统中。目前，该方法已申请国家发明专利（申请号：200510018917.5）。
