Multiparty quantum-key-distribution protocol without use of entanglement

Published Dec 20, 2007• 54 citations

Abstract

We propose a quantum-key-distribution protocol that enables three parties to agree at once on a shared common random bit string in the presence of an eavesdropper without use of entanglement. We prove its unconditional security and analyze the key rate.

Multiparty key distribution and secret sharing based on entanglement swapping

Adán Cabello

A general proof of the security against eavesdropping of a previously introduced protocol for two-party quantum key distribution based on entanglement swapping [Phys. Rev. A {\bf 61}, 052312 (2000)] is provided. In addition, the protocol is extended to permit multiparty quantum key distribution and secret sharing of classical information.

Simple Post Quantum Scheme for Higher Key Rate Multiparty Quantum Key Distribution

Abudhahir Buhari

We propose a multi-party quantum key distribution protocol which enables all the receivers can convert their respective private shared key into common secret key without use of entanglement.The main component of our protocol is a simple post quantum scheme for achieving the higher secret key rate.Efficiency of the extracted key rate is almost 100%.We assume that sender established the pre-shared private secret keys and a common secret number with the receivers.Our proposed scheme sends n strings of number to n receivers in the public channel to convert their respective shared secret key into common secret key in the presence of Eve.We also analyze the complexity of attack by the adversary to guess the secret key.

Efficient quantum key distribution secure against no-signalling eavesdroppers

Acin, A, Serge Massar, Pironio, S

By carrying out measurements on entangled states, two parties can generate a secret key which is secure not only against an eavesdropper bound by the laws of quantum mechanics, but also against a hypothetical "post-quantum" eavesdroppers limited by the no-signalling principle only. We introduce a family of quantum key distribution protocols of this type, which are more efficient than previous ones, both in terms of key rate and noise resistance. Interestingly, the best protocols involve large number of measurements. We show that in the absence of noise, these protocols can yield one secret bit per entanglement bit, implying that the key rates in the no-signalling post-quantum scenario are comparable to the key rates in usual quantum key distribution.
