中文摘要：
针对现有高质量密钥生成方法的速度慢、效率低的问题，提出了一种基于定点设备的高效随机密钥生成方法，在此基础上设计了一个高效密钥生成系统．按照FIPS 140-2标准中的规定对由该系统产生的随机密钥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密钥，可以广泛应用于各种信息安全系统中。
英文摘要：
In this paper, a new method is proposed to solve the problem that the known high quality key generate schemes are slow and inefficient. It utilizes the point device as the noise signal source and has been applied for the Chinese patent of invention （CN03128073.2）. In addition, analysis to the performance, efficiency and security about the proposed schemes has been done. The generated sequence is tested according to the standard of FIPS 140-2. The new scheme can get a batch of high quality keys fitting to the requirements for the information security system, and it is quick, secure and efficient. Further more, a truly random key generate system is build up based on the proposed scheme.
