Securing Mobile Payments in IoT Networks: Post-Quantum Challenges and Solutions

This work focuses on the security of mobile payments in Internet of Things networks, with particular emphasis on the integration of post-quantum cryptographic principles. The study adopts a modeling and simulation-based approach to analyze security challenges arising from the advent of quantum computing. The main contributions include an analytical review of post-quantum cryptographic algorithms, the identification of potential vulnerabilities in IoT-based mobile payment systems, and the development of a multivariate mathematical framework to evaluate security-performance trade-offs. Through synthetic data generation and statistical modeling, the proposed framework highlights the impact of cryptographic complexity, network latency, and device resource constraints on transaction security. The results demonstrate how post-quantum-aware security mechanisms can be optimized under practical IoT constraints. The significance of this work lies in its proactive approach to long-term security, addressing the growing vulnerability of traditional RSA- and ECC-based systems in the presence of quantum adversaries. By focusing on abstraction, modeling, and simulation, this study provides insights that support the design of future quantum-resistant mobile payment architectures in IoT environments.
