A recent review on lightweight cryptography in IoT

The Internet of Things (IoT) is a new-fashioned technology that is the future of the next era of the internet which connect various physical objects that communicate with each other without the aid of human interactions. Security plays important role in network to prevent the unauthorized access, misuses of data, monitoring and data, modification etc. All layer in IoT architecture security considered as extremely important from viewpoint of designing criteria from bottom label to top label. IoT application is becoming important in day to day lifestyle such as healthcare, smart grid, smart home, smart parking. IoT application is useful to people but if the IoT system can't protect the user data from hacker, attacks, and vulnerabilities. Lightweight encryption is a sector of a classical cryptographic algorithm Sthat is pertinent for resource constrained devices in IoT. Related work for lightweight techniques used for secure data transmission is described in this paper.
