They have the same encryption process as AES, but with parameters modified. The research of dual ciphers initially aims to find more efficient AES implementations, and later it is found that they can be used to resist side-channel attacks and for white box ciphers. In this paper, based on the rotation of columns, we propose new AES dual ciphers, which use AES directly, but with the input matrices (plaintexts and keys) and output matrix rotated. The key expansion algorithm only needs some change on the computation sequence. Because of these features, there is almost no extra cost in implementing dual ciphers and it is easy for new dual ciphers to work with other side-channel protection methods to protect AES in more dimensions.
