System, method, and apparatus for quantum key output, storage, and consistency verification

Abstract

A method for quantum key output is disclosed. The method can be implemented by a first quantum key management device. The method can comprise acquiring a first quantum key from a first quantum key distribution device, according to the obtained first key acquisition request, and storing the acquired first quantum key in a first management device address range in a first storage media, the first management device address range having the same address range indicator as a second management device address range in a second storage media for storing a corresponding second quantum key acquired by a second quantum key management device, wherein the address range indicator is one of a pair of head address and a tail address, a head address and a range length, or a head address and a length of one of the first quantum key or the second quantum key.
