Abstract

This paper proposes a modification to, BB84 style, prepare and measure quantum key distribution schemes in order to make them resistant to photon number splitting attacks in multi-photon implementations. Therefore, brighter laser pulses can be used for key transmission potentially increasing the key rate and transmission distances without the need of a repeater. Our proposal assumes a small amount of pre-shared secret information between the communicating parties similar to that used for authentication.
