AES (Advanced Encryption Standard) is a standard for encrypting electronic data. AES operates on a 44 column-major order array of bytes. The operations in the matrix are also performed on the polynomials in a special finite field and using S-box. We firstly recall necessary information about matrix algebra. In the present work, we examine the AES encryption method. We create a new encryption algorithm called matrix encryption standard (MES). MES is performed by similar steps to the AES algorithm over 16x16 matrices with elements {0,1} without using polynomials operations and S- box in the AES algorithm. So, we provide 256-bits plain text to be encrypted by passing it through certain rounds with the 16x16 matrix key. In order to decrypt the cipher text, we take the reverse of t...
