  When submitting ``Coin-Flipping-based Quantum Oblivious Transfer''
(quant-ph/0605027v4) to Indocrypt-2006, I received valuable reviews. Due to the
attacks in these reviews, my major protocols, for cheat-sensitive and
coin-flipping-based 2-1 oblivious transfers, are insecure. I would have
withdrawn the paper. But I think I'd rather post the attacks made by the
reviewer. Besides, as ``coin-flipping-based 2-1 OT'' is an important case-study
in ``Two-party Models and the No-go Theorems'' (quant-ph/0608165), the paper is
also touched by the attack. It will be reconsidered, and the case-study will be
eliminated from it. I would like to thank the ``anonymous'' reviewer for those
valuable attacks and comments.
