Abstract: This paper presents an alternative method for forming the state matrix required for AES encryption algorithm. The design uses alternative method for mapping the individual bytes of the block to different columns of the state matrix depending on previously defined encryption vector. This adds an extra layer of security to the process, but at the same time keeps algorithm simple to implement.
