摘　　要：在分析了Folded towel映射系统动力学特性的基础上,采用位序列量化算法,设计了一种新型基于离散超混沌映射的伪随机序列生成器。该伪随机序列生成器能同时生成三种伪随机序列,且均通过了NIST SP800-22随机数检验标准测试,具有接近δ函数的自相关性和接近于0的互相关性,系统密钥空间大,初值敏感性和复杂度高等特点,适合应用于信息加密。On basis of analyzing of the dynamical behaviors of a discrete hyperchaotic map, a novel pseudo-random sequence generator is designed by applying a bit sequence quantization algorithm. It can generate three pseudo-random sequences at the same time. The generated pseudo-random sequences passed SP800-22 test successfully, and they have many advantages,such as a δ-like auto-correlation, close zero cross-correlation property, large key space, great sensitivity, and high complexity. It is suitable for applications in the field of information encryption.
