Evaluating the Effects of Cryptography Algorithms on power consumption for wireless devices

Abstract :-
Security is important for wireless networks, mainly because the communications signals are openly available as they propagate through the air. The security settings can be different in many factors, but the main factors are the choice of ciphers used to provide security functions, the key length, and the number of operational rounds, packet size, and data types. These factors also have a significant impact on the energy consumption for providing security. The design of energy efficient secure protocols for wireless devices needs to understand how encryption affects the consumption of battery power with and without data transmission. The major contributions of this paper are energy-security trades off then, some suggestions for design of secure communications systems.

This paper illustrates the key concepts of security, wireless networks, and security over wireless networks. Wireless security is demonstrated by applying the common security standards like (802.11 WEP and 802.11i WPA, WPA2) and provides evaluation of six of the most common encryption algorithms on power consumption for wireless devices namely: AES (Rijndael), DES, 3DES, RC2, Blowfish, and RC6. Experimental results are given to demonstrate the effectiveness of each algorithm.
