    "abstract": "A general study of arbitrary finite-size coherent attacks against\ncontinuous-variable quantum cryptographic schemes is presented. It is shown\nthat, if the size of the blocks that can be coherently attacked by an\neavesdropper is fixed and much smaller than the key size, then the optimal\nattack for a given signal-to-noise ratio in the transmission line is an\nindividual gaussian attack. Consequently, non-gaussian coherent attacks do not\nneed to be considered in the security analysis of such quantum cryptosystems.",
