    "abstract": "We assess the security of a quantum key distribution protocol relying on the\ntransmission of Gaussian-modulated coherent states and homodyne detection. This\nprotocol is shown to be equivalent to a squeezed state protocol based on a CSS\ncode construction, and is thus provably secure against any eavesdropping\nstrategy. We also briefly show how this protocol can be generalized in order to\nimprove the net key rate.",
