Recently many substitution box based encryption algorithms ensuring privacy have been proposed. Many, chaotic map based S-boxes have been generated posing high nonlinearity and strong cryptographic properties. Encryption schemes depending on the substitution box (S-box) only are weak and easily breakable with the help of chosen plaintext and ciphertext attacks. In this work, we have completely cryptanalyzed S-box based encryption scheme successfully by two types of attacks. Cryptanalysis in both types of attacks is performed by only one selected image. Moreover, we have suggested some improvements in the algorithm to defeat attacks.

基于非线性混淆成分的加密算法的密码分析

最近，已经提出了许多确保隐私的基于替换盒的加密算法。已经产生了许多基于混沌图的S盒，这些盒具有很高的非线性度和很强的加密特性。仅取决于替换盒（S-box）的加密方案是弱的，并且在选择的明文和密文攻击的帮助下很容易被破坏。在这项工作中，我们成功地通过两种攻击对基于S-box的加密方案进行了完全加密。两种攻击中的密码分析仅由一个选定的映像执行。此外，我们提出了一些改进的算法以抵御攻击。
