Performance Analysis of AES, Blowfish and Rijndael: Cryptographic Algorithms for Audio

Abstract

Normally people share data like text, image, audio or video with others using a computer network. When these media are transmitting through the computer network, it faces various security problems for any form of data: text, image, audio or video. Information security is a challenging job while data transmission; that is why cryptography is badly required in network security. Audio encryption is very important nowadays because most of the transaction is in the form of audio. There are various algorithms available for encryption–decryption symmetric as well as asymmetric. Comparison of the performance for selected algorithms (Blowfish, AES and Rijndael) is the purpose of this research. The result shows that Blowfish performs better than AES and Rijndael.
