Implementation of AES DUKPT in Software Point of Sale: Enhancing Security in Digital Payment Systems

Pavan Kumar Joshi

Abstract: This paper explores the implementation of the Advanced Encryption Standard (AES) with Derived Unique Key Per Transaction (DUKPT) in Software Point of Sale (SoftPOS) systems. The rapid advancement of digital payment technologies necessitates robust and efficient encryption methods to ensure secure transactions. By integrating AES DUKPT, SoftPOS systems can achieve enhanced security, scalability, and compliance with industry standards. This paper delves into the architecture, key management, encryption processes, and performance evaluation of AES DUKPT within SoftPOS environments.
