Decoy state. Within quantum cryptography, the Decoy state quantum key distribution (QKD) protocol is the most widely implemented QKD scheme. Practical QKD systems use multi-photon sources, in contrast to the standard BB84 protocol, making them susceptible to photon number splitting (PNS) attacks. This would significantly limit the secure ...

The Model C used the same 10 hp motor the 1904 Model A was equipped with. Model C had a longer wheelbase than the earlier Model A. Built at the Ford Piquette Avenue Plant, it was the entry-level car in the Ford model lineup, slotting below the upscale Model B. Production ended in 1905 with approximately 1,000 cars produced (Canada production ...
