Energy Efficiency Comparison with Cipher Strength of AES and Rijndael Cryptographic Algorithms in Mobile Devices
AbstractWe analyse energy efficiency vs. cipher strenth of AES/Rijndael crypto algorithms in a mobile device with respect to block and key size. The experimental results show that Pareto-optimal solutions have equal block and key sizes. We also propose three energy/security profiles for the users of mobile devices. As decryption operation requires 14% more energy than encryption, the results of energy consumption measurements when performing data encrypion can be used to predict energy consumption of decryption operation.
