摘要：Oblivious Transfer and Bit Commitment are typical foundation agreements to secure multi-party computations. Both of them are hotspots in the field of information security. Using of the quantum channel and the principles of the quantum mechanics, Quantum Oblivious Transfer can be achieved higher security and higher efficiency than the Classic Oblivious Transfer, while it also has a unique advantage in found eavesdropping. Quantum Bit Commitment scheme can be used to build up zero knowledge proof, verified secret sharing, throwing coins etc agreements. We had given out a very novel QOT scheme based on three-particle entangled states. And we had investigated unconditional secure Quantum Bit Commitment existence. At last, we constructed a new bit commitment model � double prover bit commitment. The Quantum Bit Commitment Protocol can be resistant to errors caused by noise.
