AES Modes of Operation

Abstract

Cryptography is the science of secret codes. Previously we used DES algorithms in order to secure but cannot encrypt completely. Thus, we referred AES Algorithms to create a ciphertext in encryption and is given as an input in decryption. In present scenario, everyone sharing their data in online using internet alsoonline transactions like e-banking for money transfers, in shopping malls, restaurants, and many more. While transferring a huge amount or any confidential data there are many chances to hack the data.There are different modes of operations used in AES in accordance with the efficiency to blur the data. The design has been done in VHDL (Very High-Speed Integrated Circuit Hardware Description Language) and simulated and synthesized using Xilinx.
