摘要 在对换位加密技术研究的基础上,提出了一个基于混沌系统的动态换位加密方案。该方案通过二进制数据转换、数据替换及动态换位等加密步骤,很好地实现了明文的混淆与扩散。与传统的换位加密相比,新方案不仅有较大的密钥空间,而且产生的换位序列具有很强的随机性。理论分析及实验结果表明,给出的新方案可以抵抗多种已知的密码攻击,克服了传统换位加密技术的弱点,具有较高的安全性。 The technology of transposition cipher is discussed firstly and a novel dynamic transposition cipher based on chaotic systems is presented.The cipher permute plaintext into ciphertext by converting plaintext into binary data,data substitution and dynamic transposition.The plaintext is sufficiently diffused and confused.Compare with traditional transposition ciphers,the new scheme had larger key space and the transposition sequences are stochastic.Theoretical analysis and experimental results demonstrate that the cipher can resist many kinds of known attack and overcome the weakness of fixed transposition encryption.It is more security than traditional transposition ciphers.
