Abstract

In this paper we provide a determined key distribution protocol using orthogonal product states in which people can share a predetermined string as the key. The fundamental principles of quantum mechanics guarantee that the protocol is unconditionally secure. There are no entangled states or complex quantum operations needed in our protocol. So it’s easy to carry out in practice and robust against possible noise and attacks.

Determined Key Distribution Protocol Using Non-Orthogonal Quantum States

Xiao Yu Li, Lei Zhao

In this paper we provide an quantum determined key distribution protocol using non-orthogonal quantum states. Two parts can build a key by exchanging some qubits. The principles of quantum mechanics guarantee that the protocol is unconditionally secure. No one except the two parts can get the key. There are no entangled states and complex quantum operations except measurements needed in our protocol. So it is easier to carry out and more robust in practice.

Quantum Key Distribution Protocol Using Orthogonal Product Quantum States

Dexi Zhang

Quantum key distribution is the most secure technology to distribute a secret key. There is a set of orthogonal product states in a two-qubit three-state quantum system which can show nonlocality. This paper provides a quantum key distribution protocol based otn the nonlocality of such system. The two parties establish the key by exchanging quantum qubits and performing the collective measurement on them. The laws of quantum mechanics guarantee that this protocol is unconditionally secure. No other people can get the key without being found. There are no entangled states and quantum operations needed in the protocol. So it is easier to carry out in practice. And it can gain high reliability and robustness.

Quantum Determined Key Distribution Scheme Using Quantum Teleportation

Xiaoyu Li, Nianqing Wan, Dexi Zhang

In this paper we provide a quantum determined key distribution protocol using quantum teleportation. Unlike the previous protocols which produce a random string in the key distribution process as the key, in our protocol the two parties can share a predetermined binary string as the key with the help of quantum teleportation. The principles of quantum mechanics guarantees that no other people can get the key. So the protocol is unconditionally secure.

Quantum Determined Key Distribution Scheme Using the Bell Measurement

Xiaoyu Li, Dexi Zhang

In this paper we provide a quantum determined key distribution scheme. Unlike the previous schemes which produce a random string in the key distribution process as the key, in our scheme the two parties can share a predetermined binary string as the key with shared entangled states and performing CNOT operation and the Bell state measurement. The principles of quantum mechanics guarantees that no other people can get the key. So the scheme is unconditionally secure.

Multiparty Quantum Determined Key Distribution Protocol Using Open-Destination Teleportation

Qiu Yu Zhao, Xiao Yu Li, De Xi Zhang

A multiparty quantum determined key distribution protocol using open-destination teleportation is presented in this paper. Four parties can build a key using the technology of open-destination teleportation. Unlike in the previous protocols in which the key is a random string built in the process of key distribution, the key can be a determined string in our protocol. We prove that our protocol is guaranteed to be unconditionally secure by the laws of quantum mechanics.

Multiparty quantum determined key distribution protocol using GHZ states

Xiaoyu Li, Dexi Zhang

A multiparty quantum determined key distribution protocol using GHZ(Greenberger-Horne-Zeilinger) states is presented in this paper. Three parties can build a key with the help of GHZ states. The key can be a determined string in our protocol while the key is a random string built in the process of key distribution in previous protocols. We prove that our protocol is guaranteed to be unconditionally secure by the laws of quantum mechanics.
