    "abstract": "This is a study of the security of the Coherent One-Way (COW) protocol for\nquantum cryptography, proposed recently as a simple and fast experimental\nscheme. In the zero-error regime, the eavesdropper Eve can only take advantage\nof the losses in the transmission. We consider new attacks, based on\nunambiguous state discrimination, which perform better than the basic\nbeam-splitting attack, but which can be detected by a careful analysis of the\ndetection statistics. These results stress the importance of testing several\nstatistical parameters in order to achieve higher rates of secret bits.",
