Energy and Area Costs of Lightweight Cryptographic Algorithms for Authenticated Encryption in WSN

Operation time for the implemented sensor node configurations. It is important to remark that our experiment is a case study, it is expected that the lifetime of a real-world application would be longer, and thus the time differences would be greater. The sensor node prototypes were configured on the XC6LX16-CS324 FPGA embedded in the Nexys 3 development board. A 6V and 1Ah lead acid battery was used as power source. An XBee transmitter was connected to the FPGA board and also sourced from the 6V battery.
