The vast increase in the development of Human Sensor Networks (HSN) and nodes has led to the increase in the exchange of the data among the sensor devices.Usually, the sensor devices will be having limited resources such as low battery power, less memory, etc. and should be capable to handle sensitive and private data.Normal encryption methods will not be suited for these sensor devices as they require large resources.For this reason, lightweight block ciphers are used for encrypting data on sensor devices.These algorithms should balance the security requirements along with energy consumption.In this paper, different design parameters and performance metrics for computing the energy being consumed by an encryption algorithm have been discussed.Lightweight block ciphers may work on different block sizes.To have a fair assessment among the ciphers, energy cost has been considered in order to encode one bit of plaintext.Energy per bit is considered as an important performance metric in measuring the energy efficiency of a cipher algorithm in low resource constraint devices.
