Abstract

In this paper, a mechanism of manipulating data means encrypting and decrypting data in Electronics Code Book (ECB) mode is introduced using AES cryptographic algorithm. AES is a symmetric key encryption algorithm which process data in block of 128 bits using key expansion module which uses key scheduling. Implementation of AES encryption engine needs to consume a large number of hardware resources. This paper enlightens on higher performance and security without key expansion module. This design uses same key for each operation of Rijndeal Algorithm by using look up table for Substituting bytes for encryption as well as for decryption by which logic resources have been largely reduced. Experimental results prove that this implementation with the ECB mode which uses same key provides the ability to secure data in a better efficient way.
