%X <span style=\"font-size:14px;\">本文研究了一类二维时变离散时空系统的混沌性，并分析了它的多种伪随机性能。在此基础上，结合拉丁方构造的基本密码系统，设计了一种新的多元流密码算法。将该算法应用于数字图像加密之中，并与二元流密码系统的加密效果进行了对比。实验结果表明新算法具有足够大的密钥空间，并具有良好的加密性能和安全性。</span><br />
<span style=\"font-size:14px;\">This paper studies the chaos of a class of two-dimensional time-varying discrete spatiotemporal systems and analyzes its several pseudorandom properties. On this basis, combined with a basic cipher system constructed by a Latin square, a new multi-bit stream cipher algorithm is designed out and is applied in digital image encryption. Compared with the encryption effect of the single-bit stream cipher algorithm, simulations show that the new algorithm has a large enough key space, good encryption performance and security.</span>
