Benchmarking Security Computations on Wireless Devices
Divyesh Shah, Sheng Zhong · 2006
Many applications using cryptographic solutions on wireless devices choose one cryptographic technique over another with the assumption of it being more battery power efficient than the other. We present extensive benchmark test results for various cryptography techniques measuring the battery consumption of each technique on wireless devices in terms of number of computations per unit percent battery drain so that many of these assumptions could be better supported with strong evidence. The benchmark tests are performed on two wireless devices: a HP iPaQ PDA and a Dell Inspiron notebook. The cryptography techniques considered include DES, RC2, Rijndael , RSA encryption, MD5 and SHA hashing, and DSA, RSA signature algorithms. We present analysis of our results and a very useful comparison of these techniques enabling future research efforts to make a better decision while selecting cryptographic methods based on concrete results.
