The internet of things (IoT) technology has changed the modern digital world. Devices connected to the IoT have sensors embedded within them. Data sharing among IoT devices needs some security protocol to maintain the privacy and confidentiality of data. Traditional public-key cryptographic techniques have been used to achieve data security while transmitting data. The application of traditional public-key cryptographic techniques is not feasible in an IoT environment. Therefore, there is a requirement for lightweight cryptographic approaches which produce a feasible solution. Elliptic curve-based cryptographic techniques are used to provide privacy and authenticity of data. The lightweight properties of elliptic curve cryptography (ECC) reduce the communicational and computational complexities of resource-constrained IoT devices. This paper presents an analytical approach for discussing various elliptic …
