Experimental implementation of B92 Quantum key distribution protocol

Abstract

Quantum key distribution is a technique that permits the secure distribution of a bit string, used as key in cryptographic protocols. The security is guaranteed by suitable coding of the information in a quantum property and from the fact that a quantum cannot be both split and cloned. In this paper, we give details and show the results of an experimental realization of the B92 quantum key distribution protocol in 1550 nm telecom window.Index Terms-quantum key distribution, single-photon detector, light polarization.

A Study on “Security of Cyber-Physical Systems in the Cloud”

“…QKD has been proved to be secure against adversaries using future computational improvements. Mosca, Stebila and Ustaoglu [4] described BB84 QKD protocol which is then integrated with traditional AKE models. Their experiments proved that QKD can withstand future advances in computing arena.…”

“…In the process the test is considered successful if the estimated error rate is less. 4. At the end, Alice and Bob can obtained a secret key using other bits after subjecting them to privacy amplification and error correction.…”

“…The QKD protocol here considered is the B92 protocol [2][3][4]. The sender (Alice) will send MMW/THz single-photons with polarization randomly chosen in the set {0, /4}.…”

Discrete Variable Quantum Key Distribution in Millimeter-Wave and THz Regions

“…uantum key distribution (QKD) was the first commercially available quantum technology, implemented using the infrared portion of the electromagnetic spectrum, that allows secure communication between spatially distant users [1][2][3][4][5]. It has been successfully implemented in fiber-based and freespace optical networks.…”
