Abstract

The efficacy of the Advanced Encryption Standard (AES) algorithm has made it very attractive for data encryption. As a result of this, it has been employed by many large organizations for safeguarding files in any binary format. It makes use of a symmetric key to achieve successful data encoding. To encrypt a file, it uses different key sizes. Although a bigger key size increases the degree of unpredictability, it also increases the encryption time. AES utilizes Add round key, Byte substitution, Shift rows and Shift column matrix operations together with a Galois Field computation in Modulus two (MOD 2). This paper shows the step by step process of how data is encrypted using the AES.

Keywords

AES, Add round key, Byte substitution, Galois Field, Shift rows and Shift column.
