    "abstract": "We present security proofs for a protocol for Quantum Key Distribution (QKD)\nbased on encoding in finite high-dimensional Hilbert spaces. This protocol is\nan extension of Bennett\u0027s and Brassard\u0027s basic protocol from two bases, two\nstate encoding to a multi bases, multi state encoding. We analyze the mutual\ninformation between the legitimate parties and the eavesdropper, and the error\nrate, as function of the dimension of the Hilbert space, while considering\noptimal incoherent and coherent eavesdropping attacks. We obtain the upper\nlimit for the legitimate party error rate to ensure unconditional security when\nthe eavesdropper uses incoherent and coherent eavesdropping strategies. We have\nalso consider realistic noise caused by detector\u0027s noise.",
