Quantum key relay protocols between any terminals in Internet
互联网中任意终端间量子密钥中继协议

This paper proposed the concepts and protocols of quantum key relay. Using quantum entanglement properties or quantum teleportation, quantum key sharing between the two non-adjacent terminal equipments can be achieved, i. e. , quantum key relay, and ultimately achieve the quantum secret sharing between any terminals in the Internet, furthermore, they had the unconditional security.
