The inverse S-box is used in the decrypting function inv_cipher to revert the substitution carried out via the S-box. The corresponding AES-Matlab function declared in Line 1 of Listing 7 takes the Sbox (s_box) as its input and generates the in

能够用MATLAB实现DES算法加密，包含密钥生成和S盒的生成函数(DES algorithm can be encrypted with MATLAB, including key generation and S-box generation function.)

SM4加密算法的matlab语言实现，采用s盒变换、轮函数等。(SM4 encryption algorithm is realized by MATLAB language, using S-box transformation, wheel function and so on.)
