Smart cities, fueled by the Internet of Things (IoT), promise urban efficiency and convenience. However, it has also exposed vulnerabilities in the security and privacy of sensitive data transmitted and stored within these interconnected networks. The increasing frequency of cyberattacks and data breaches underscores the pressing need for innovative solutions to enhance the security of smart city IoT systems. This paper introduces a novel approach to bolstering IoT security in smart cities by adapting quantum cryptography principles. Leveraging quantum steganography, we conceal sensitive data within quantum streams. The proposed model provides a comprehensive solution that ensures the confidentiality, integrity, and authenticity of data within smart city IoT ecosystems. By combining quantum steganography, reversible decoding, customized encryption, privacy amplification, and cryptographic verification, this protocol fosters trust among stakeholders and supports the secure evolution of urban environments. This research offers a blueprint for securing IoT in smart cities, fostering trust, and enabling the safe evolution of urban environments.
