An Effective Lightweight Cryptographic Algorithm to Secure Internet of Things Devices

Abstract

The Internet of Things (IoT) connects billions of devices all over the world that are currently connected to the internet. IoT is essentially a combination of constrained devices that share sensitive data with each other without human involvement. Various security and privacy concerns exist with such a large number of connected devices, as they have low inbuilt resources. Hence, it is imperative to provide security solutions for such devices to secure them. This implies that the authentication factor protects the security and privacy of these devices and data by playing a vital role in data integrity. We have been analyzed in this paper the various lightweight solutions with the authentication requirements in IoT applications. This study has indicated that the top security issue is to provide less computation and be resistant to attacks, such as replay attacks, man-in-the-middle, forgery and chosen-ciphertext attacks, and denial of service (DoS) attacks.
