摘　　要：通过对基于Logistic映射的混沌加密算法原理的分析,提出了一种基于Logistic映射的交叉加密算法。该算法利用2个一维混沌系统对明文进行交叉异或和求余运算,使用2个混沌系统扩大了密钥空间,并增加了密钥的复杂性,提高了抗破译强度。实验结果表明此算法运算速度快,密文对密钥敏感。该算法具有较好的安全性且易于实现。Analyses the encryption algorithm principle based on the Logistic Mapping,proposes a kind of cross-encryption.This algorithm using two one-dimensional chaotic systems to do Cross-XOR operation and mod-operation,it expanded the key space and the complexity of the increased key,improving the strength of ciphers.Experimental results show that this method has better safety,efficiency and is easy to be realized.
