Sensor devices have critical resource constraints such as processing speed, memory size and energy supply. Especially, energy consumption affects the network lifetime so that energy efficiency is an important requirement for Wireless Sensor Networks (WSNs). It means that it is a considerable matter to choose the energy- and a memory-efficient cryptographic algorithm suitable for WSNs. In this paper, an Energy Efficient Encryption Algorithm with 64-bit block length and 128-bit key length with basic operations like eXclusive-OR (XOR) and shifting is implemented. It provides low-resource hardware implementation, which is suitable to sensor devices.
