Insecurity of Quantum Two-Party Computation with Applications to Cheat-Sensitive Protocols and Oblivious Transfer Reductions
Oblivious transfer (OT) is a fundamental primitive for secure two-party computation. It is well known that OT cannot be implemented with information-theoretic security if the two players only have access to noiseless communication channels, even in the quantum case. As a result, weaker variants of OT have been studied. In …
