Query: A Private Quantum Bit String Commitment   We propose an entanglement-based quantum bit string commitment protocol whose
composability is proven in the random oracle model. This protocol has the
additional property of preserving the privacy of the committed message. Even
though this property is not resilient against man-in-the-middle attacks, this
threat can be circumvented by considering that the parties communicate through
an authenticated channel. The protocol remains secure (but not private) if we
realize the random oracles as physical unclonable functions in the so-called
bad PUF model with access before the opening phase.
