The development of technology at the present time leads to an increase in the use of electronic commerce due to the increase in demand processes, whether selling or buying goods, products, services, or payment requests, and that the transfer of information the merchants is sensitive and important information, and this information or operations may be subject to penetration or attacks. In this research, we designed a protocol that integrates the Fernet algorithm and the ElGamal algorithm, and we use the Data Leakage Detection Technology (DLD) to safeguard e-commerce transaction data. This protocol provid high security for information, and the integration of algorithms provides high security and strong performance for information transactions that are difficult to hack. We incorporate encryption algorithms to achieve a high level of security and performance. The proposed protocol is higher in security and performance than the algorithms of previous studies.

Electronic-commerce (e-commerce) has become a provider of distinctive services to individuals and companies due to the speed and flexibility of transferring orders and completing commercial deals across far and different places. However, due to the increasing attacks on penetrating transaction information or tampering with e-commerce requests, the interest in protecting this information and hiding it from tamperers has become extremely important. In addition, hacking these deals can cause a huge waste of money and resources. Moreover, large numbers of connected and disconnected networks can cause significant disruption to the built-in security measures. In this paper, we propose to design a protocol to protect transaction information based on ElGamal, advanced encryption standard (AES) and Chinese remainder theorem (CRT) techniques. In addition, our protocol ensures providing scalability with high-performance security measures. We combine these algorithms with a robust methodology that supports the balance of performance and security of the proposed protocol. An analysis of our results proves that our protocol is superior to existing security protocols. [ABSTRACT FROM AUTHOR]
