A lightweight digital signature generation mechanism for authentication of IoT devices

Abstract

Internet of Things (IoT) is a rising technology which is several devices is connected through the Internet. The devices communicate with each other over the network and produce a new reality to us. In order to enjoy this new environment, the security of the devices is much essential. The lightweight cryptography is superior to the conventional cryptography. In hardware implementations, chip size and energy consumption are less compared to the general cryptography. In software implementations, the smaller code and RAM size are preferable for lightweight applications. The primitives of the lightweight cryptography are encryption, hash functions, and digital signature. The sensor data is encrypted by using hash functions and digital-signature. In this project, we are using the above methodologies analyzing the security in IoT.
