Design and Application of an International Trade Trading Platform Based on ElGamal and Elliptic Curve Cryptography

Network security has attracted numerous people and significantly develop a subject in international trade actions. Conventional trade procedure suffers from the large number of problems about the mediators, data latency and privacy. The development of blockchain technology have become potential to solve the problems through transforming the business procedure over the enterprise borders in different industries. To overcome this issue, this research proposes the hybrid cryptographic algorithm of ElGamal and Elliptic Curve Cryptography (EECC) approach for the analysis of international trade trading system. ECC provides effective security by smaller key sizes, designing it complex for attackers to break the encryption through brute-force attacks. ElGamal extends an additional layer of security through allowing an encryption according to Diffie-Hellman key exchange, further securing data. This research significantly studied the blockchain in international trade application, developed its privacy and effective distributed network and verified its effectiveness. The results shows that the proposed method attains better throughput of 210p/s on a centralized authorization manager.
