Multiparty Quantum Determined Key Distribution Protocol Using Open-Destination Teleportation
Qiu Yu Zhao, Xiao Yu Li, De Xi Zhang · Applied Mechanics and Materials · 2010
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.
