Analysis of Quantum Key Distribution Protocols

Essential role of Internet-based communication is the security of information. Classical Cryptography is based on mathematical models and computational complexity to compute the secret key. It does not provide enough security because finding a fast method to calculate the secret key will compromise the security of the system. Quantum Key Distribution is one of the most promising methods which provide unconditional security. Quantum Key Distribution (QKD) uses a quantum property in exchanging information called photons, as carriers of information in security systems, and QKD cannot separate from protocols BB84, B92 and BBM92. In this paper, we are testing the probability error comparison of BB84 protocol, B92 protocol, and BBM92 using QuVis simulator software. The results show that the B92 protocol is more relevant in detecting eavesdropping in lower error rates than the other two protocols.
