    "abstract": "We demonstrate high-rate randomized data-encryption through optical fibers\nusing the inherent quantum-measurement noise of coherent states of light.\nSpecifically, we demonstrate 650Mbps data encryption through a 10Gbps\ndata-bearing, in-line amplified 200km-long line. In our protocol, legitimate\nusers (who share a short secret-key) communicate using an M-ry signal set while\nan attacker (who does not share the secret key) is forced to contend with the\nfundamental and irreducible quantum-measurement noise of coherent states.\nImplementations of our protocol using both polarization-encoded signal sets as\nwell as polarization-insensitive phase-keyed signal sets are experimentally and\ntheoretically evaluated. Different from the performance criteria for the\ncryptographic objective of key generation (quantum key-generation), one\npossible set of performance criteria for the cryptographic objective of data\nencryption is established and carefully considered.",
