Quantum key distribution method and system and service station

The invention provides a quantum key distribution method and system and a service station. A quantum key is used as data, and the quantum key is encrypted through a non-quantum encryption strategy, sothat the transmission of the quantum key is realized, and thus a purpose of transmitting the quantum key by using a non-quantum communication network can be achieved, and the application range of thequantum key is expanded. 本申请提供了种量子密钥的分发方法及系统、服务站，将量子密钥作为数据，使用非量子加密策略加密量子密钥，实现量子密钥的传递，因此，能够实现使用非量子通信网络传输递量子密钥的目的，扩展了量子密钥的应用范围。
