Asymmetric Bidirectional Quantum Communication with Device Authentication in IoT

Quantum communication holds great potential for enhancing the security and efficiency of the Internet of Things (IoT). However, existing schemes often overlook device identity authentication, leaving systems vulnerable to unauthorized access, and rely on third-party controllers, which increase complexity and undermine trust. This paper proposes a novel asymmetric bidirectional quantum communication scheme tailored for IoT, integrating device identity authentication and information transmission without requiring third-party controllers. We provide a detailed description of the scheme’s application scenarios in IoT, conduct a security analysis of the identity authentication module, and experimentally validate the feasibility of the information transmission module. Additionally, we analyze the impact of quantum noise on the proposed scheme and compare it with existing approaches, highlighting its advantages in terms of resource consumption and efficiency.
