    Lightweight AES Algorithm for Resource Constraint Devices
    (IUT, CSE, 2016-11-20) Chowdhury, Arnab Rahman; Mahmud, Junayed
    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.
