标题： Cryptanalysis of a family of self-synchronizing chaotic stream ciphers

摘要： 单峰映射已被广泛用作新加密策略的基础。 最近，文献中提出了一种流密码，其密钥流基本上是（单参数）逻辑斯蒂映射或帐篷映射的符号序列。 在本研究中，对密钥流进行了深入分析，揭示了存在一些严重的安全问题。 显示英文摘要

摘要： Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic sequence of the (one-parameter) logistic map or of the tent map. In the present work a thorough analysis of the keystream is made which reveals the existence of some serious security problems
