    "abstract": "By simulating four quantum key distribution (QKD) experiments and analyzing\none decoy-state QKD experiment, we compare two data post-processing schemes\nbased on security against individual attack by L\\\"{u}tkenhaus, and\nunconditional security analysis by Gottesman-Lo-L\\\"{u}tkenhaus-Preskill. Our\nresults show that these two schemes yield close performances. Since the Holy\nGrail of QKD is its unconditional security, we conclude that one is better off\nconsidering unconditional security, rather than restricting to individual\nattacks.",
