Applying Detection Leakage on Hybrid Cryptography to Secure Transaction Information in E-Commerce Apps

Abstract

Technology advancements have driven a boost in electronic commerce use in the present day due to an increase in demand processes, regardless of whether goods, products, services, or payments are being bought or sold. Various goods are purchased and sold online by merchants (M)s for large amounts of money. Nonetheless, during the transmission of information via electronic commerce, Ms’ information may be compromised or attacked. In order to enhance the security of e-commerce transaction data, particularly sensitive M information, we have devised a protocol that combines the Fernet (FER) algorithm with the ElGamal (ELG) algorithm. Additionally, we have integrated data leakage detection (DLD) technology to verify the integrity of keys, encryptions, and decryptions. The integration of these algorithms ensures that electronic-commerce transactions are both highly secure and efficiently processed. Our analysis of the protocol’s security and performance indicates that it outperforms the algorithms used in previous studies, providing superior levels of security and performance.

Secure Key-Based Substitution-Boxes Design Using Systematic Search for High Nonlinearity

“…Table 11 provides a comprehensive listing of the parameters employed in the proposed method of S-box creation, along with their corresponding ranges and key spaces. The magnitude of the key space offers a significant protection against unauthorized access attempts [73,74]. The sheer number of possible keys makes it highly improbable for an attacker to stumble upon the correct key by random guessing or exhaustive search.…”
