Efficient Implementation of Advanced Encryption Standard

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. This can be achieved by using Cryptographic techniques. The earlier encryption algorithm is Data Encryption Standard (DES) which has several loopholes such as small key size and sensible to brute force attack etc. and it cannot provide high level, efficient and exportable security. These loopholes overcome by a new algorithm called as Advanced Encryption Standard (AES). It was created by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, replacing the old Data Encryption Standard (DES). The Federal Information Processing Standard 197 used a standardized version of the algorithm called Rijndael for the Advanced Encryption Standard. AES was successful because it was easy to implement and could run in a reasonable amount of time on a regular computer.
