What is the AES MixColumn Sublayer?
Monday, 11 September 2023
by Silvio Pereira
The MixColumn sublayer is a important component of the Advanced Encryption Standard (AES) block cipher cryptosystem. It plays a significant role in achieving the desired level of security by introducing non-linearity into the encryption process. This sublayer involves a non-linear transformation that can be represented by a 4×4 matrix multiplication. To understand the MixColumn sublayer,
