Implementation of Secure Quantum Protocol using Multiple Photons for Communication
This addresses security risks in cloud server communication by introducing a novel quantum protocol, though it appears incremental as it builds on existing quantum cryptography concepts.
The paper tackles the vulnerability of current quantum cryptography protocols, like BB84, to siphoning attacks from multiple photons, by implementing a three-stage quantum protocol in free-space that allows secure communication using multiple photons.
The paper presents the implementation of a quantum cryptography protocol for secure communication between servers in the cloud. As computing power increases, classical cryptography and key management schemes based on computational complexity become increasingly susceptible to brute force and cryptanalytic attacks. Current implementations of quantum cryptography are based on the BB84 protocol, which is susceptible to siphoning attacks on the multiple photons emitted by practical laser sources. The three-stage protocol, whose implementation is described in this paper, is a departure from conventional practice and it obviates some of the known vulnerabilities of the current implementations of quantum cryptography. This paper presents an implementation of the three-stage quantum communication protocol in free-space. To the best of the authors' knowledge, this is the first implementation of a quantum protocol where multiple photons can be used for secure communication.
