    "abstract": "The ``impossibility proof\u0027\u0027 on unconditionally secure quantum bit commitment\nis critically analyzed. Many possibilities for obtaining a secure bit\ncommitment protocol are indicated, purely on the basis of two-way quantum\ncommunications, which are not covered by the impossibility proof formulation.\nThey are classified under six new types of protocols, with security proofs for\nspecific examples on four types. Reasons for some previously failed attempts at\nobtaining secure protocols are also indicated.",
