Embodiment Construction
[0038] The design scheme of the present invention will be described in detail below with reference to the accompanying drawings and examples, but the present invention is not limited to this embodiment.
[0039] In this example, if figure 1 As shown, a blockchain-based quantum key distribution method is applied by the blockchain, user U a , user U b , set in user U a Nearby key pool C 1 , set in user U b Nearby key pool C 2 , and key pool C 1 Manager M 1 , key pool C 2 Manager M 2 In the public network environment formed, the user U a Nearby key pool C 1 and user U b Nearby key pool C 2 The same configuration, and connected through the public quantum channel; as figure 2 As shown, the quantum key distribution method is carried out according to the following steps:
[0040] Step 1: Initialization phase:
[0041] User U a Nearby key pool C 1 and user U b Nearby key pool C 2 After invoking the quantum key distribution protocol and generating key streams respec...
