Introduction to 3DES

The presented simulation results showed that 3DES has a better performance result with ECB and CBC than other common encryption algorithms used. In this paper we present a performance evaluation of selected symmetric encryption algorithms. The selected algorithms are AES, DES, 3DES, Blowfish, RC2, and RC4. In case of changing key size, it can be seen that higher key size leads to clear change in the battery and time consumption. In future the work may be extensive by including the schemes and techniques over different types of data such as image, sound and video and rising a stronger encryption algorithm with high speed and minimum energy consumption.
