AES and Confidentiality from the inside out

Information Confidentiality has a prominent significance in the study of ethics, law and most recently in Information Systems. With the evolution of human intelligence, the art of cryptography has become more complex in order to make information more secure. There are arrays of encryption systems those are being deployed in the world of Information Systems by various organizations. However, for the wider use, we need to adapt to a particular encryption method and standard. This paper is intended to be an easy to follow tutorial on the principles of Information Security, Information Confidentiality and their underlying standards. This paper also thoroughly explains the inner working of an encryption standard known as Advanced Encryption Standard or AES.
