Eavesdropping Detection Technique using Differential Space Time Relativistic Quantum Key Distribution in Public Key Infrastructure

Relativistic Quantum Key Distribution (RQKD) enhances secure communication by combining quantum mechanics with relativity. It uses relativistic properties, like the invariance of the speed of light, to ensure secure key exchange. Challenges may still persist and eavesdropping can still happen due to various factors including Timing manipulation, physical equipment vulnerabilities and Relativistic exploitation. To mitigate such security vulnerabilities, in this proposed eavesdropping detection work, additional parameter namely Space-Time coordinates of the sender and receiver are introduced into the Relativistic QKD. Finally, derived result shows that our proposed Space-Time Relativistic QKD (STR-QKD) can enhance the security with the additional Space-Time constraints for all systems including AI systems.
