Comparison of Data Encryption Algorithms

COMPARISON OF DATA ENCRYPTION ALGORITHMS Simar Preet Singh, and Raman Maini University College of Engineering, Punjabi University, Patiala, INDIA, E-mail: [email protected], [email protected] This paper tries to present a fair comparison between the most common and used algorithms in the data encryption field. The two main characteristics that identify and differentiate one encryption algorithm from another are its ability to secure the protected data against attacks and its speed and efficiency in doing so. This paper provides a performance comparison between four of the most common encryption algorithms: DES, 3DES, Blowfish and AES. The comparison has been conducted by running several encryption settings to process different sizes of data blocks to evaluate the algorithm’s encryption/decryption speed. Since our main concern here is the performance of these algorithms under different settings, the presented comparison takes into consideration the behavior and performance of the algorithm when different data loads are used. Simulation has been conducted using C# language.
