A Low-Cost Implementation of Advance Encryption Standard

Abstract

The fast development of the Internet enables the information to be easily shared on a global network, however, it also raises the concerns about the secure of the information especially the sensitive data such as passwords, bank accounts, personal information and so on. One method to protect the sensitive data is using symmetric-key block cypher before and after sending it over the network using same secret key. Advanced Encryption Standard (AES) is currently considered as best symmetric-key block cipher. With the block size of 128-bits ...
