Post-quantum cryptography: Reshaping the future of identity and access management

Banerjee, Tuhin (2025) Post-quantum cryptography: Reshaping the future of identity and access management. World Journal of Advanced Engineering Technology and Sciences, 15 (2). pp. 350-356. ISSN 2582-8266

The emergence of quantum computing presents significant challenges to existing Identity and Access Management (IAM) systems, particularly concerning the security of current cryptographic algorithms. As quantum computers evolve, traditional public-key cryptography methods like RSA and ECC face increasing vulnerability, necessitating a transition to quantum-resistant alternatives. This document explores the critical intersection of post-quantum cryptography and IAM, examining the transformation required in security frameworks to maintain resilience in a quantum-enabled future. The discussion encompasses the evolution of quantum threats to current IAM implementations, the development of post-quantum cryptographic solutions, the essential transformation of IAM infrastructure, and the integration of advanced technologies, including artificial intelligence and quantum-safe authentication mechanisms. Special attention is given to practical implementation considerations, including hybrid authentication models and the modernization of Public Key Infrastructure (PKI) systems to ensure continued security in the post-quantum era.
