Matrix Based Efficient ECC Technique For Text Encryption
We propose a novel mapping method based on invertible matrix and random sequence for converting alphanumeric
characters of the plaintext message onto the (x; y) coordinates of Elliptic Curve defined over the prime eld GF(p). The mapped
points are further encrypted with Elgamal Cryptosystem. Finally we illustrate the implementation of our cryptosystem based into an
elliptic curve characterized by the equation y2 = x3 - x + 19 (mod 71). The cryptosystem provides sufficient security against
cryptanalysis at low computational overhead, a brute force attack to break the cryptosystem is almost infeasible.
