Linear Attack on Second Round Mini Advanced Encryption Standard (AES)

Linear attack is primarily introduced for DES encryption system by Matsui. This particular cryptanalysis was based on linear approximation of nonlinear S-boxes within the algorithm. This kind of attack is then deployed for many other block ciphers. This paper describes linear attack on second round Mini-AES. By using this cryptanalysis, it is possible to attack on full round of Mini-AES algorithm. Undoubtly, one of the most important result of this cryptanalysis is that, it will be possible to better understanding linear attack on Rijndael.
