Energy consumptions analysis for a class of symmetric encryption algorithm

Due to the increased demand on wireless devices and their applications, the necessity for efficient and secure encryption algorithms is critical. A secure encryption algorithm is considered energy efficient if it uses a minimum number of CPU operations. In this paper we use numerical calculations to analyze the energy consumption for a class of encryption algorithms. We compute the number of arithmetic and logical instructions in addition to the number of memory access used by each of the algorithms under study. Given some information about the microprocessor used in encryption, we can compute the energy consumed per each instruction and hence compute the total energy consumed by the encryption algorithm. In addition, we use computer simulations to compare the energy loss of transmitting encrypted information over the Wireless channel. Therefore, in this paper we introduce a comprehensive approach where we use two approaches to analyze the energy consumption of encryption algorithms.
