The rapid convergence of sixth-generation (6G) networks and the Internet of Things (IoT) offers enormous potential for ultra-reliable, low-latency, and massive device connectivity. However, this integration also raises security and privacy concerns, particularly in light of new threats from quantum computing that could undermine traditional cryptography. The architecture of quantum-safe IoT networks that can withstand post-quantum security threats is thoroughly discussed in this review. It addresses the challenges related to how to use blockchain technology to provide decentralized trust as well as secure transactions, how to use post-quantum cryptographic algorithms to protect data confidentiality, and the best way to use a trust management architecture to improve identity verification, authorization, and authentication in the diverse IoT environment. The paper then examines scalability considerations, resource constraints, and interoperability problems that impact safe IoT deployments in the 6G era. This work serves as a roadmap for researchers and practitioners who aim to create robust and future IoT infrastructure and then maintain their security in a post-quantum world by integrating recent research patterns, solution development, and considerations related to real-world implementation.
