Privacy and the Quantum Internet

The increasing popularity of 6G communication within the Internet of Vehicles (IoV) ecosystem is expected to induce a surge in both user numbers and data volumes. This expansion will cause substantial challenges in ensuring network security and privacy protection, as well as in addressing the associated issue of inadequate cloud computing resources. In this article, we propose a Quantum Efficient Privacy Protection (QEPP) protocol that leverages reversible information hiding in quantum point clouds. This protocol utilizes quantum communication technology in edge-to-cloud communication of the IoV to transmit sensitive information embedded in quantum state data, thereby ensuring privacy protection. It employs quantum error-correction coding and efficient coding techniques to extract information and recover the carriers. In addition, the protocol utilizes an improved quantum Grover algorithm in the cloud to accelerate the processing speed of quantum data. By addressing security vulnerabilities and improving cloud-computing capabilities, the QEPP can effectively accommodate critical requirements, including precision, timeliness, and robust privacy protection.

Quantum internet is an innovative approach to secure communication. Quantum internet is the next revolution in technology that enables the devices to perform operations that are beyond the classical internet. Quantum internet with quantum cryptography is one of the best solutions for secure data communication. Quantum internet uses the fundamental laws of quantum physics, which make it secure against sophisticated network attacks. In this research, the authors described quantum cryptography, which enhances the secure transmission over quantum internet using cryptographic protocols. These protocols use random bits transformations, which prevent attackers to make out the patterns of random bits transformations. Also, they introduced the conceptual OSI model for quantum internet, which makes it easy to understand the working of the quantum internet at different layers. Quantum internet can be implemented in intelligence network, satellite communication, critical infrastructure, etc. This can mark a significant change in secure communication.
