An Efficient Method for text Encryption using Elliptic Curve Cryptography

Elliptic curve cryptography (ECC) is an emerging and efficient cryptography technique which can be applied in various fields of application such as sensor network, network security, authentication, signature verification and in the different applications of the internet of things (IOT). ECC is lightweight, efficient and more secure compare to any other public key cryptography. Different methods have been proposed in the literature to convert input message to elliptic curve point but all of them lack in security, scalability and computationally inefficient for large input size. So, a scalable and computationally efficient algorithm is highly required. In this paper, we propose two different algorithms for input message to elliptic curve point conversion which will reduce communication cost and computational cost of encryption and decryption. The experimental result also shows that the proposed algorithms give better performance and best suitable for large size input text compared to any other existing algorithms.
