With the rapid progression of digital data exchange in electronic way, security of information is becoming more important in data storage and transmission. Therefore numerous ways of protecting information are being utilized by individuals, businesses, and governments. Cryptography has come up as a solution which plays a vital role in information security system against malicious attacks. This security system uses some algorithms to scramble data into scribbled text which can be only being decoded or decrypted by party those possesses the associated key. In this paper, a most widely used symmetric encryption techniques i.e. Advanced Encryption Standard (AES) have been implemented using MATLAB software.
