Analysis of Algorithms for Effective Cryptography for Enhancement of IoT Security

Abstract

The Internet of Things has emerged as one of the most prevalent technologies of the current times, finding its place in a myriad of applications and is widely used for digitization and automation applications such as smart city development, automated monitoring systems, healthcare, energy management and much more. With more devices being connected to the Internet, one of the biggest challenges faced by the Internet of Things surfaces—privacy and security risks. The vulnerability of IoT devices and networks have been brought to light, presenting a threat to the integrity of data. Cryptography has proved itself as a method to secure communication channels and data, as a way to ensure IoT security. In this paper, we aim to compare cryptographic algorithms, namely—AES, DES, RSA and lightweight cryptographic algorithm Fernet, to determine which cryptographic algorithm is the most efficient and secure, and can thereby minimize the risk to data integrity and security in IoT applications.
