    "abstract": "We investigate the security of continuous-variable (CV) quantum key\ndistribution (QKD) using coherent states and reverse reconciliation against\nGaussian individual attacks based on an optimal Gaussian $1 \\to 2$ cloning\nmachine. We provide an implementation of the optimal Gaussian individual\nattack. we also find a Bell-measurement attack which works without delayed\nchoice of measurements and has better performance than the cloning attack.",
