Practical Quantum Key Distribution based on the BB84 protocol
Quantum Cryptography features a unique way of sharing a random sequence of bits between users with a certifiably security not attainable with either public or secret-key classical cryptographic systems. This is achieved by means of Quantum Key Distribution (QKD) techniques, which rely on exploiting the laws of quantum mechanics [1]. Indeed, only systems based on QKD techniques can offer uncondi...
متن کاملThe FPGA Implementation of Quantum Key Distribution Based on BB84 protocol
A new QKD implementation scheme of BB84 protocol is introduced based on FPGA. Firstly, the overall design method and the functional division are described in detail. Then, the logic design of the sub-module are significantly studied, including random data module, laser source drive module, error correcting module, receiver/transmitter interface module, extracting original key module and error r...
متن کاملQuantum Key Distribution via BB84 An Advanced Lab Experiment
Electronic communication has become one of the main pillars of modern society and their ongoing boom requires the development of new methods and techniques to secure data transmission. This has been the goal since the onset of cryptography in ancient times. Cryptography may be defined as the art of writing (encryption) and deciphering (decryption) messages in code in order to ensure their confi...
متن کاملSimulation of BB84 Quantum Key Distribution in depolarizing channel
College of Information and Electronic Engineering, Zhejiang Gongshang University, Hangzhou, 310018, China [email protected] Abstract: In this paper, we employ the standard BB84 protocol as the basic model of quantum key distribution (QKD) in depolarizing channel. We also give the methods to express the preparation and measurement of quantum states on classical computer and realize the si...
متن کاملRandomness determines practical security of BB84 quantum key distribution
Unconditional security of the BB84 quantum key distribution protocol has been proved by exploiting the fundamental laws of quantum mechanics, but the practical quantum key distribution system maybe hacked by considering the imperfect state preparation and measurement respectively. Until now, different attacking schemes have been proposed by utilizing imperfect devices, but the general security ...
