Multifarious Mapping Schemes on Elliptic Curve Cryptography for IoT Security

Abstract

Elliptic Curve Cryptography (ECC) is a current area of enquiry in the domain of Cryptography. ECC is beneficial in various schemes of cryptography due to its lowered key size and rapid generation of key. It is suitable for IoT devices to provide security. Many IoT devices have restricted amount of storage and processing ability. They frequently need to run on low power. Heavy encryption dependent approaches are not a good fit for these constrained devices. They are incapable of performing complicated encryption and decryption quick enough to be able to secure data in real-time transmission. Transformation of text messages to elliptic curve points has always been enigmatic. Comparing to other cryptographic algorithms the arithmetic involved in elliptic curve cryptography is computationally less complicated. This paper provides an overview of elliptic curves, different mapping schemes and their application in cryptography. The emphasis is on the performance gains to be acquired by using elliptic curve cryptography as an alternative to conventional cryptosystem like RSA.
