信息安全系统中一种实用的随机数产生方法

Random mumber generation method of information security system

介绍一种利用电路内部噪声信号做成随机序列发生器的设计和工作原理,并对它输出序 列进行密码学意义上的随机性和安全性分析。这种随机数发生器可以集成在芯片内,也可以利用该 芯片做成一种基于微机总线的随机数产生卡。所以,它可以很方便地用于各种信息安全系统中,为这 些系统的安全提供有力的保障。

The design and principle of a random number generator made by circuit noise signal was introduced,analyzing the randomness and security of its output sequence in cryptography.It may be integrated into chip, a board based on micro-computer bus may also was made by using this chip.So it is may applied to all kinds of information security system to assure their security.
