INTRODUCTION decryption. RSA signatures, a variant of this In an era dominated by digital transactions, the algorithm, provide a robust mechanism for need for robust security measures to safeguard authenticating the origin and integrity of digital sensitive data and ensure the integrity of e- messages, thereby ensuring the trustworthiness of commerce transactions has never been more e-transactions. pressing. With the proliferation of online banking, e-commerce platforms, and electronic In this paper, we propose a trustworthy approach communications, the risk of cyberattacks, data to fortifying e-transactions using RSA signatures. breaches, and fraudulent activities looms large. In By leveraging the inherent security features of RSA response to these challenges, cryptographic encryption, e-transaction systems can enhance techniques play a pivotal role in fortifying e- their resilience against unauthorized access, data transactions and instilling trust in digital tampering, and fraudulent activities. The use of commerce. RSA signatures enables parties involved in e- transactions to verify the authenticity of digital One such cryptographic technique that stands out messages and establish trust in the identity of the for its efficacy and reliability is RSA (Rivest– sender. Shamir–Adleman) encryption, particularly in the form of RSA signatures. RSA is an asymmetric Throughout this paper, we will delve into the cryptographic algorithm that utilizes a pair of keys principles of RSA signatures, their application in e- – a public key for encryption and a private key for transaction security, and the benefits they offer in https://www.theamericanjournals.com/index.php/tajiir 1 THE USA JOURNALS THE AMERICAN JOURNAL OF INTERDISCIPLINARY INNOVATIONS AND RESEARCH (ISSN- 2642-7478) VOLUME 06 ISSUE07 safeguarding sensitive data and preventing fraud. involved, comprising a public key for encryption By exploring real-world scenarios and case studies, and a private key for decryption.
