Abstract

One or more embodiments of the present specification provide a quantum key distribution method and system. The method comprises: deploying a QKD node and a subordinate node located in a key transmission domain of the QKD node; generating a quantum key by the QKD node pair, constructing a key pool, and storing the quantum key generated by the QKD node pair in the key pool; constructing a key pool slice of the subordinate node according to a received key pool slice construction instruction, and storing a part of quantum keys shared between the subordinate node pairs in the key pool slice; and in response to successful construction of the key pool and the key pool slice, transmitting the quantum key to the subordinate node in the key transmission domain. According to the embodiment, multi-level distribution of quantum keys can be realized.

Description

technical field [0001] One or more embodiments of this specification relate to the field of information security technology, and in particular to a quantum key distribution method and system. Background technique [0002] With the development of technologies such as quantum computers with powerful computing capabilities, traditional data encryption methods based on algorithm complexity will be difficult to continuously guarantee data security. Quantum Key Distribution (Quantum Key Distribution, QKD) technology can provide an information-theoretic secure way to generate symmetric keys, resisting attacks and eavesdropping on communication links. QKD devices can provide quantum keys to ensure communication security. However, due to the high cost of QKD devices, the deployment of QKD devices has limitations in terms of energy consumption, mobility, and quantum channel construction. It is difficult to configure QKD devices for each node. With the expansion of network scale and t...
