The advent of quantum computing presses this need further. This research presents a comprehensive framework for a digital identity system using post-quantum cryptographic paradigms to ensure long-term security and privacy. By integrating quantum-resistant algorithms for primitives such as key encapsulation mechanisms, digital signatures, and advanced hashing techniques, the proposed system delivers secure identity management. The framework is designed to withstand potential threats posed by quantum computers while maintaining compatibility with existing infrastructure. We evaluate the system's performance through a rigorous security analysis of the proposed algorithm by time leakage vectors and statistical analysis thereof, concluding that there are no implementation attack vectors independent to the proposed algorithm and that it's security is reliant on its components only.
