Enhanced Biometric Key Exchange Protocol (EBKEP) with TOTP for 2FA

The increasing computational power and advent of quantum computing necessitate advancements in cryptographic protocols.This paper presents the Enhanced Biometric Key Exchange Protocol (EBKEP) with Time-Based One-Time Password (TOTP) generation for two-factor authentication (2FA), leveraging the uniqueness of biometric data combined with advanced cryptographic techniques.Using face recognition as a case study, EBKEP aims to provide a secure, efficient, and user-friendly method for key exchange, ensuring robust security even in the face of emerging quantum threats.This paper details the design, implementation, quality checks, and security features of EBKEP, highlighting its potential as a next-generation key exchange protocol.The results show significant improvements in security, user convenience, and performance, validated through a comprehensive test plan and procedure.
