Cheat sensitive quantum bit commitment (CSQBC) loosens the security requirement of quantum bit commitment (QBC), so that the existing impossibility proofs of unconditionally secure QBC can be evaded. But here we analyze the common features in all existing CSQBC protocols, and show that in any CSQBC having these features, the receiver can always learn a(More)
We study the entanglement-based attack on a recently proposed quantum oblivious transfer (OT) protocol (Nagy and Nagy in Quantum Inf Process 15:5037, 2016). While in secure OT, Bob’s probability of obtaining Alice’s secret bit unambiguously should be limited to 50%, we show that if Bob has the technology to handle 5-body entangled states in the current(More)
