Abstract

The invention discloses a route distribution method based on an encryption service and electronic equipment, and relates to the technical field of communication, and the method comprises the steps: determining candidate routes corresponding to the encryption service; determining the number of available keys in a key pool corresponding to each candidate route; selecting a candidate route with the maximum available key number as a target route based on the available key number; and transmitting the encrypted service based on the target route. According to the invention, candidate routes of whichthe available key numbers are from large to small are successively selected as target routes based on the available key numbers; the encryption service is transmitted based on the target route, so that the encryption service can preferentially distribute the encryption service to the target route with a large number of available keys according to the number of the available keys, and quantum keyinjection and consumption in a quantum key pool in the route are more balanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for route distribution based on encrypted services and electronic equipment. Background technique [0002] Quantum key distribution (English: quantum key distribution, referred to as QKD), is to use the characteristics of quantum mechanics to ensure communication security. It enables communicating parties to generate and share a random, secure key to encrypt and decrypt messages. [0003] At present, quantum key distribution technology usually directly generates keys through negotiation between source and sink nodes. Specifically, a quantum key pool can be constructed on each pair of quantum transceiver nodes and the quantum communication routes (quantum channel + classical channel) occupied by them. The key space in the key pool can store quantum keys continuously generated between quantum node pairs to ensure the security of key distribution. [0004] However,...
