DES and AES performance evaluation

Abstract

In these days use of digital data exchange is increasing day by day in every field. Information security plays very important role in storing and transmitting the data. When we transmit a multimedia data such as audio, video, images etc. over the network, cryptography provides security. In cryptography, we encode data before sending it and decode it on receiving, for this purpose, we use many cryptographic algorithms. AES and DES are most commonly used cryptographic algorithms. AES provides the encryption to secure the data before the transmission and DES also provides security as AES. In this paper we discussed AES and DES and their comparison using MATLAB software .After applying AES and DES, we compare their result on the basis of avalanche effect, simulation time and memory required by AES and DES.

E-Banking Security using Cryptography, Steganography and Data Mining

“…This data is decrypted using the AES decryption algorithm [8]. After decryption of data the first task done is validation of user card details wherein the card number, cvv, expiry date and name is verified.…”

“…Along with the card details the user location is also detected in terms of latitude and longitude along with current date and time. All this data is then encrypted using AES algorithm [8] and this encrypted data is then embedded in an image using F5 steganography algorithm [10]. This image is used by the user for carrying out the respective transaction thus, ensuring that user details are securely transmitted over a network.…”

“…The card details, user location in terms of latitude and longitude and the current date and time are then encrypted using the AES encryption algorithm [8]. The key used for encryption in the AES algorithm used above is further encrypted using the RSA algorithm [9].…”

Time performance analysis of advanced encryption standard and data encryption standard in data security transaction

“…The area of AES application researches in AES time taken in encrypting and decrypting process can be found in [12][13][14][15][16][17]. The AES also had been used to test the efficiency of data security with optimal data throughput [18][19].…”
