Improved Card Payment Security Using RSA Cryptography

Abstract

E-commerce has introduced a novel method of conducting transactions worldwide through the utilization of the internet. The effectiveness of e-commerce hinges significantly on the strategic application of information technology. Over time, the volume of sensitive e-commerce data transmitted via the internet and computer networks has witnessed a substantial surge. Consequently, every company is driven to ensure the security of its e-commerce information. It is imperative to safeguard e-commerce data as it traverses the internet and computer networks. The proliferation of credit card fraud and identity theft is a direct result of the internet's status as a public network teeming with countless users. Among these users are malicious individuals, often referred to as crackers or hackers, who exploit inadequate internet security measures to perpetrate credit card fraud and identity theft in various ways. As a result, concerns about executing secure and convenient online monetary transactions have escalated. The significance, risks, and elevated priority of securing e-commerce money transfers have turned this domain into a prominent subject of research within modern computer science and informatics. While the e-commerce industry has made strides in addressing security concerns within its internal networks, safeguarding consumers' security remains in its infancy, posing a hindrance to e-commerce advancement. Consequently, there is an emerging need for technological solutions that can comprehensively secure e-commerce transaction data on a global scale, employing appropriate data security technology. The proposed technological solution to address this security challenge is the utilization of the RSA cryptosystem. This research paper is dedicated to the objective of enhancing the security of e-commerce information transmitted across computer networks and the internet through the application of RSA cryptography. The research data mainly is drawn from secondary source which include current journal research articles and lecture notes. For the novel design to emerge and properly modeled using UML tools such as class diagram, entity relation (E-R) diagram. Additionally, for the database design, the front end was developed using PHP, CSS5, JavaScript, and HTML5. The back end utilized PHP, Apache, and MySQL. This configuration aims to create a system that operates efficiently and effectively.
