Abstract:
As digital infrastructures grow increasingly complex and cyber threats become more sophisticated, the Zero Trust Architecture (ZTA) model has emerged as a foundational paradigm in cybersecurity. Meanwhile, the advent of quantum computing poses existential threats to traditional cryptographic systems, necessitating a paradigm shift towards Post-Quantum Cryptography (PQC). This paper investigates the convergence of ZTA and PQC, assessing their compatibility, challenges, and future prospects. It presents an in-depth evaluation of existing classical cryptographic mechanisms, identifies quantum vulnerabilities, and explores the integration of NIST-recommended PQC algorithms within ZTA frameworks. Through a hybrid methodology combining simulation-based validation and architectural modelling, this research illustrates that implementing PQC within ZTA not only reinforces identity-centric security but also enables cryptographic agility to future-proof digital systems. The study concludes that the synergy between PQC and ZTA represents a critical evolution in cybersecurity, calling for immediate policy-level and technical integration across sectors.
