Using Quantum Oblivious Transfer to Cheat Sensitive Quantum Bit Commitment
Jakoby, Andreas
Liskiewicz, Maciej
Madry, Aleksander
We define $(varepsilon,delta)$-secure quantum computations
between two parties that can play dishonestly to maximise
advantage $delta$, however keeping small the probability
$varepsilon$ that the computation fails in evaluating correct value.
We present a simple quantum protocol for computing
one-out-of-two oblivious transfer that is
$(O(sqrt{varepsilon}),varepsilon)$-secure.
Using the protocol as a black box we construct a scheme for
cheat sensitive quantum bit commitment which guarantee that
a mistrustful party has a nonzero probability of detecting a
cheating.
