Abstract:
Our world is slowly approaching brink of mankind's next technological revolution since
the conception of Internet of Things(IoT) emerges. The realization of IoT requires an
enormous amount of sensor nodes which have limited battery power, memory, compu
tational latency and communication bandwidth to acquire inputs from the connected
objects. In the current developments of the resource constraint environments, the trend
is shifted towards lightweight cryptographic algorithm. Many lightweight cryptograpic
algorithms have been developed and also existing algorithms are modied in terms of
resource constraint environment. In this paper we analyzed a very popular block cipher
AES-128 and tried to make it lightweight regarding energy consumption. We also studied
some other lightweight block cipher which are optimized in terms of energy, power and
memory.
