Attack Strategy

We present a new non-Gaussian quantum key distribution (QKD) protocol using squeezed states. Compared with a binary modulation, the efficiency can be improved when a four alphabetic letters modulation is chosen. We then analyze the security of the protocol under a collective entangling cloner attack, which is a powerful attack strategy in continuous variable QKD. We also show how the modulation coefficient affects the key rate, then the key rate can be maximized by choosing an optimal coefficient.
