    "abstract": "We clarify the argument on the how (nonlocal) degenerate Bell measurement can\nbe replaced by local measurements in the modified Lo-Chau quantum key\ndistribution protocol. Discussing security criterion for users, we describe how\neavesdropper\u0027s refined information on the final state is not helpful. We argue\nthat current discussions on the equivalence of the Bell and the local\nmeasurements are not clear. We show how the problem of equivalence can be\nresolved using the fact that eavesdropper\u0027s refined information is not helpful\nfor her.",
