We introduce a protocol for QKD based on reusable entangledstates. In this protocol, the EPR pairs act as a quantum key toencode and decode information particles. And only an informationparticle travels between the legitimated users. This improves thesecurity and efficiency of communication. In addition, we showthat its extension to a new QSS protocol is also secure and efficient. |
