Encryption/Decryption of X-Ray Images Using Elliptical Curve Cryptography with Issues and Applications

Abstract

Elliptic Curve Cryptography is a public key cryptography scheme which is leading now days because of its great advantages (small key size, less time for encryption, no solution to Discrete Logarithmic problem, impossible time taken for brute force attack) for handheld, low memory, portable and small devices. Applying Elliptic Curve Cryptography on text and image gives almost equal performance. In this paper we are summarizing that how Elliptic Curve Cryptography encrypts and decrypt text data and image. Operations responsible for encryption are point multiplication, point addition, point doubling, and point subtraction are explained in detail. One more thing which is very necessary in decryption of the Elliptic Curve Cryptography that is Discrete Logarithmic Problem which is also explained briefly and many more comparative study about Elliptic Curve Cryptography advantages, Disadvantages, Elliptic Curve Cryptography attacks and its applications comparing with other Encryption Algorithms.
