提出了一种基于混沌映射迭代的分组密码方案。该算法利用实数混沌映射产生的随机二进制序列对明文块进行密钥相关移位置换，然后利用经典的混沌掩蔽技术进行加密。仿真结果表明，该方案的性能和安全性优于现有的算法。文中还详细讨论了该方案的优点和安全性。(c)2005年由Elsevier B.V.出版
A block cryptographic scheme based on iterating a chaotic map is proposed. With random binary sequences generated from the real-valued chaotic map, the plaintext block is permuted by a key-dependent shift approach and then encrypted by the classical chaotic masking technique. Simulation results show that performance and security of the proposed cryptographic scheme are better than those of existing algorithms. Advantages and security of our scheme are also discussed in detail. (c) 2005 Published by Elsevier B.V.
