A study on the power consumption of using cryptography algorithms in mobile devices

In this work, a novel lightweight and low energy encryption algorithm for voice over wireless networks is being developed and tested. The new encryption algorithm has to meet the QoS requirements of voice traffic and to be suitable for wireless devices. The goal of the research was to reduce the execution time and power consumption of the encryption process compared with the standard algorithm and at the same time at least to maintain or to increase its security level. The proposed algorithm employs similar methods with those used in the Advanced Encryption Standard algorithm (AES), with some changes and enhancements considering the limitations of wireless devices. The test results show significant improvements in new design metrics. A range of simulation scenarios are setup; testing data is analyzed to test delay, energy and security. Also, the comparison between the new algorithm and the standard one shows a significant amount of time and energy consumption reduction being achieved (approximately 35%), with good-level of complexity, making it more suitable for the wireless environment.

“…The algorithm's power consumption can be measured by calculating the total of computing cycles which are used in processes related to cryptographic tasks. For the calculation of the total energy and cost of encryption, the following equations are used similar with those defined in [10]. Where 𝐵 𝑐𝑜𝑠𝑡_𝑒𝑛𝑐𝑟𝑦 is a basic cost of the encryption process (ampere-cycle), 𝜏 is the total number of clock cycles, 𝐼 is the average current drawn by each CPU clock cycle, 𝑇 𝑒𝑛𝑒𝑟𝑔𝑦_𝑐𝑜𝑠𝑡 is the total energy cost (ampere-seconds), 𝐹 is the clock frequency (cycles/sec), and 𝐸 𝑐𝑜𝑠𝑡 (Joule) is the energy cost (i.e.…”
