摘要
The National Institute of Standards and Technology(NIST) announced Rijndael as the new Advanced Encryption Standard(AES). DES algorithm was the predecessor of AES algorithm which was insecure because of force attacks. The AES is a symmetric block cipher. This encryption process consists of key expansion, Add Round Key, sub bytes, Shift Rows and mix column. This paper presents the survey of efficient cryptographic algorithms and implementation of efficient Mix Column in AES algorithm. Mix column transformation is the linear operation in which the state array matrix is multiplied with constant square matrix. LUT architecture is to be introduced in Mix Column in order to reduce the area. Also pipelining architecture is to be introduced in order to reduce the de;ay since the multiplication is the slow process which in-turn reduces the speed of whole AB encryption process.
