Abstract

The invention discloses a route distribution method and electronic equipment based on encrypted services, and relates to the field of communication technology, including: determining candidate routes corresponding to encrypted services; determining the number of available keys in a key pool corresponding to each candidate route; based on The number of available keys selects a candidate route with the largest number of available keys as a target route; and transmits the encrypted service based on the target route. The present invention sequentially selects candidate routes with the number of available keys ranging from large to small as the target route based on the number of available keys; transmits encrypted services based on the target route, so that the encrypted service can be prioritized according to the number of available keys Encryption services are allocated to target routes with a large number of available keys, which makes the quantum key injection and consumption in the quantum key pool in the route 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,...
