Abstract :

Elliptic Curve Cryptography (ECC) has attracted the attention of researchers and product developers due to its robust mathematical structure and highest security compared to other existing algorithms. This paper produced a new approach for elliptic curve cryptosystem take behavioral symmetric cryptographic system instead of asymmetric cryptographic system by investigate from Metaheuristic algorithms (Greedy Randomized Adaptive Search Procedure (GRASP) and Variable Neighborhood Search(VNS)) in order generate symmetric mask key (i.e. produced symmetric key consist of more the one ECC points). The proposed approach aim to combine between the features of Elliptic Curve Discrete logarithm, mathematics and Metaheuristic algorithms (GRASP and VNS) to produce robust symmetric mask key. The most important feature of this mask key it must have a minimum correlation among points . (i.e. Minimum correlation provide randomness on the mask key) . The proposed approach tested using visual prolog language by performs the encryption and decryption processes using text and gives efficient results.
