Performance Analysis of AES and TwoFish Encryption Schemes

The two main characteristics of a good encryption algorithm are: Security and Speed. Usually security algorithms have to be embedded in a variety of applications like e-banking, online shopping, mails etc. So they should be fast as well as secure in different environments. In this paper, we do security v/s performance analysis of two algorithms Two fish and AES. First, we will discuss security issues of both algorithms by considering their safety factor. Then we study encryption speed of both algorithms by encrypting different type of data (text, image, audio) and analyze their performance in terms of throughput of every algorithm on different size of RAMs. The results show the relationship between performance of algorithms and size of RAM and type of data.
