摘要： 基于Logistic映射、Henon映射产生两个混沌密钥序列,然后对读取的明文位串进行交替加密。设计的加密算法不但能抵抗唯密文攻击,而且能有效地抵抗选择明文攻击。结果表明,该算法具有良好的密码学特性。

Abstract: Two chaotic secret-key sequences are generated based on Logistic function and Henon function , which is used to alternantly encryt text sequence. The encryption algorithm can effectively resist cipher-text-only attack and chosen-plaintext attack.The results show that the algorithm can meet the requests in cryptography.
