Secure and authenticated quantum secret sharing

Abstract

We propose here a quantum secret sharing scheme that works for both quantum and classical secrets. The proposed scheme is based on both entanglement swapping and teleportation together. It allows sender to encrypt his/her secret and simultaneously distribute decryption information of the encrypted secret among distant parties where decryption shares are nonlocally correlated with each other. Two-fold quantum non-local correlations, generated through entanglement swapping and then teleporting quantum states over swapped maximally entangled pairs, guarantee both authentication and secrecy of the secret from internal as well as external eavesdroppers. For classical secrets, we demonstrate a direct (2,2) quantum secret sharing scheme where neither pre-shared key nor physically secure quantum/classical channel are required. The same scheme turns out to be a (5,5) quantum secret sharing scheme for quantum secrets if sender and receivers have private quantum/classical channels among them.

A novel approach for secure multi-party secret sharing scheme via Quantum cryptography

Noor ul Ain

Classical secret sharing proposed by Shamir used classical computational power in classical cryptography to achieve secret key sharing, but with the advent of quantum systems, computational power can be overruled. To ensure a secure secret sharing scheme independent of computational power, a scheme independent of computational complexity is needed to achieve security. This paper will provide a protocol dependent on inherent secure nature of quantum cryptography (quantum no cloning theorem and quantum measurement rule). A secure multiparty quantum secret sharing scheme has been proposed to ensure that no one can eavesdrop or extract any share of the secret message via inherent security provided by quantum entanglement swapping and quantum teleportation. Entanglement swapping is a process that allows two non-interacting quantum systems to be entangled. Whereas, Quantum teleportation allows a party to send a qubit to another entangled party without sending the qubit over the channel. Moreover, in order to ensure security against possible active attacks, sender himself will generate and distribute EPR pairs to be used in the scheme. Result will be a secure multiparty QSS scheme which will be secure against internal and external eavesdropping, masquerading and brute-force attacks.

Authenticated Multiparty Secret Key Sharing Using Quantum Entanglement Swapping

Muneer Alshowkan, Khaled M. Elleithy

In this paper we propose a new protocol for multiparty secret key sharing by using quantum entanglement swapping.Quantum Entanglement swapping is a process that allows two non-interacting quantum systems to be entangled.Further, to increase the security level and to make sure that the users are legitimate, authentication for both parties will be required by a trusted third party.In this protocol, a trusted third party will authenticate the sender and the receiver and help them forming a secret key.Furthermore, the proposed protocol will perform entanglement swapping between the sender and the receiver.The result from the entanglement swapping will be an Einstein-Podolsky-Rosen (EPR) pair that will help them in forming and sending the secret key without having the sender to send any physical quantum states to the receiver.This protocol will provide the required authentication of all parties to the trusted party and it will provide the required secure method in transmitting the secret key.

Three-Party Quantum Secret Sharing Based on Secure Direct Communication

Liu Yanyan, Cheng-Qian Xu

Inspired by quantum secure direct communication and quantum dense coding, we present a three-party quantum secret sharing (QSS) scheme by quantum teleportation. After performing the rectilinear basis or diagonal basis measurement randomly for the eavesdropping check to ensure the security of the quantum channel, the sender encodes the secret messages directly on a series of Einstein-Podolsky-Rosen (EPR) pairs and transmits them to the receivers by quantum teleportation. Neither of the receivers can decode the secret messages on his own even if they collaborate. Only the two receivers combine their measurement results with the sender's result, can they recover the secret messages. In this scheme, one qubit can encode two bits of classical information because quantum dense coding is introduced. Using quantum teleportation, the distinct advantage of this scheme is that there is not the transmission of qubits carrying the secret messages in the quantum channel, it is absolutely secure for QSS if a perfect channel is used.

Advanced Multiparty Quantum Secret Sharing using Entanglement Swapping

N.T.V. Luu, S. Shimamoto

A multiparty quantum secret sharing scheme is proposed to utilize the magic properties of entanglement swapping. In this scheme, a set of (2N-1) EPR pairs is used to encode and distribute a secret message to (N-1) parties. Each secret message will be split into (N-1) packets. By performing the local unitary operations and entanglement swapping, each classical bit packet will be encoded secretly into Bell states so no subset of parties but their entire cooperation can read out the original secret message. The security of this proposed scheme is also considered.

New quantum secret sharing protocol based on entanglement swapping

Dan Liu

The insecurity of the protocols for quantum secret sharing(QSS) based on entanglement swapping was analyzed,and a new method of QSS based on entanglement swapping was proposed.The entanglement states were all generated by the sender,and the order of two photons sent to the same agent was randomly changed.After the photons arrived at the receiver,for the detection mode,the order of the two photons was announced,so that the two parties detected the security of the quantum channel;for the information mode,the two receivers respectively did Bell measurement on the two photons they owned,and then communicated through classical channel to share the secret key with the sender.Analysis results show that this protocol not only ensures the validity and security of the shared information,but also only uses the entanglement states of two photons without unitary operation.
