Security analysis of quantum key distribution on passive optical networks.
Needs for providing security to end users have brought installation of quantum key distribution (QKD) in one-to-many access networks such as passive optical networks. In the networks, a presence of optical power splitters makes issues for secure key rate more important. However, researches for QKD in access networks have mainly focused on implementation issues rather than protocol development f...
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 کاملMutual Authentication Mechanism using Pre-Shared Key and BB84 Quantum Key Distribution for Quantum Cryptography Communication
It is believed that the quantum cryptography based on quantum key distribution achieves unconditional security. However, the additional authentication mechanism applied to the quantum cryptography needs to be studied since it is difficult for the quantum cryptography alone to prevent manin-the-middle attacks. Thus, we propose two authentication mechanisms combined with modern cryptography that ...
متن کاملPractical 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 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...
