    "abstract": "We derive a proof of security for the Differential Phase Shift Quantum Key\nDistribution (DPSQKD) protocol under the assumption that Eve is restricted to\nindividual attacks. The security proof is derived by bounding the average\ncollision probability, which leads directly to a bound on Eve\u0027s mutual\ninformation on the final key. The security proof applies to realistic sources\nbased on pulsed coherent light. We then compare individual attacks to\nsequential attacks and show that individual attacks are more powerful.",
