A Comparative Study of RSA and ECC in Modern Network Security

Abstract

With the exponential growth of e-commerce and digital financial services, ensuring privacy in online transactions has become a critical concern. Cryptographic techniques offer robust solutions to protect sensitive user data, maintain confidentiality, and prevent unauthorized access during online financial exchanges. This paper reviews key cryptographic mechanisms such as end-to-end encryption, zero-knowledge proofs, homomorphic encryption, and secure multi-party computation that enhance privacy in online transactions. Additionally, it discusses the challenges in implementing these solutions at scale and their implications for regulatory compliance and user trust. The study concludes by outlining future research directions and best practices to balance privacy with usability in online financial ecosystems.
