He watched her dance, a random cipher drawing its signature across the time-slopes of this dissolving yantra, a symbol in a transcendental geometry.

他目视着她翩翩起舞，一个随机密码在这渐渐消融的印度教具的时间坡上画上了它的签名，那是超越几何中的一个符号。

In many cipher system, the pseudo random sequence generator is an important part in system security.

在许多密码系统中，伪随机序列生成器是系统安全的一个重要组成部分。

Then a chaotic stream cipher based on the pseudo-random number generator is designed, which has high security, low cost and easy realization proved by some experiments.

接着我们设计一种基于该伪随机数产生器的流密码。实验结果证明，该流密码具有安全性高、代价低和实现特性好的特点。
