Multi-photon quantum key distribution based on double-lock encryption

We present a quantum key distribution protocol based on the double-lock cryptography. It exploits the asymmetry in the detection strategies between the legitimate users and the eavesdropper. With coherent states, the mean photon number can be as larger as 10.
