摘　　要：由于混沌信号的隐蔽性、不可预测性、高度复杂性和易于实现等特性,基于混沌系统的加密算法也得到了广泛的研究。提出了一种基于Cat映射和改进的Logistic映射双混沌系统的数字混沌加密算法,并对算法的安全性和加密性能进行了分析。结果表明:算法具有较高的强度和较快的加密速度,可以应用于实时性较高的场合。Further research has been done on chaos-based encryption algorithm since it was presented, Some algorithms with good security features were also introduced before. At this time, a kind of chaotic encryption algorithm based on Cat map and improved Logistic map have been put forward. Some analyses regarding security and encryption have been presented as well. The analytic results indicate the algorithm have good features both in security and encryption. It is also appropriate for real time encryption,
