A modernistic architecture of masked Advanced Encryption Standard algorithm for SAN

The present information and technology processed by computers to access the private information like video conferencing, account status in bank, e – transaction of money and business deals through internet for all these encryption of the information in various forms are necessary. So to protect the information from different attacks using symmetric or asymmetric key encryption by adding the random value to the intermediate result is called masking. In terms of computational complexity symmetric key algorithm is less complex than the asymmetric or multiple key algorithms. The aim is to provide the data security to the storage area network and also the proposed method is to optimize the masked AES with the unrolled structure and it can be achieved through mapping operation. Hence to optimize the area of masked AES only needs to map the plain text and masking values from Galois Field 256 (GF (2 8 )) to Galois Field 16 (GF(2 4 )) once at the start of the operation and map the cipher text back from Galois Field 16 to Galois Field 256 once at the end of the operation. So just moving masking operation as well as the inverse mapping operation outside the masked advanced encryption standard algorithm round function area can
