Quantum Bit Commitment Combining with BB84 Protocol

We proposed a new quantum hit commitment scheme in which secret key need not to be provided by other quantum key distribution system. We can get the bit commitment with probability p by adding a waiting time in a frame during operating the BB84 protocol. Then the measurement outcomes can he encrypted by one-time pad with the key generated by 01384 protocol. We can also obtain the redundant secret keys to encrypt other information in this quantum key distribution system. The new scheme can be used to perform routing operation by which the source can be made sure that the virtual circuits it chosen doesn't influence on other relay routes in a large-scale trusted relay based quantum network.
