A Performance Evaluation Of Common Encryption Techniques With Secure Watermark System (Sws)

Abstract

ABESTRACT Ciphering algorithms play a main role in information security systems. Those algorithms consume a significant amount of computing resources such as CPU time, memory, and battery power. This research tries to demonstrate a fair comparison between the most common algorithms and with a novel method called Secured Watermark System (SWS) in data encryption field according to CPU time, packet size and power consumption. It provides evaluation of four of the most common encryption algorithms namely: AES (Rijndael), DES, Blowfish, and Secured Watermark System (SWS). A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different data types, and finally encryption/decryption speed. In addition compared with different platforms such as Windows 8, Windows XP and Linux Experimental results are given to demonstrate the efficiency and performance of each algorithm. KEYWORDS AES, DES, Blowfish, Secured Watermark System (SWS) and Computer Security.
