Abstract

In today’s world most of the communication is done using electronic media. Data Security plays a vital role in such communication. Hence, there is a need to protect data from malicious attacks. Cryptography is the study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication and data origin authentication. In data and telecommunications, cryptography is necessary when communicating over any unreliable medium, which includes any network particularly the internet. Advanced Encryption Standard (AES), also known as Rijndael, is an encryption standard used for securing information which is defined by The National Institute of Standard and technology (NIST) of United States[1][5][9]. AES is a block cipher algorithm that has analyzed extensively and is now used widely[13]. AES involves the sequence of four primitive functions: Sub Bytes, Shift Rows, Mix Column and Add Round Key. This paper presents some modifications to make AES more secure.
