Abstract

The invention discloses a satellite management method based on a blockchain and a physical unclonable function. The method comprises the steps of dividing a plurality of satellite virtual trust regions, building an intra-domain blockchain network in each satellite virtual trust region, and building an inter-domain blockchain network between the satellite virtual trust regions; setting a domain main satellite in intra-domain satellites contained in each satellite virtual trust area; enabling the domain main satellite to create and deploy a first intelligent contract of the intra-domain block chain network so as to record identity authentication data of an out-domain satellite to be added into the satellite virtual trust area, service transaction data of the out-domain satellite and the intra-domain satellite and power withdrawal data of the out-domain satellite; and enabling a ground workstation to create and deploy a second smart contract of the inter-domain blockchain network so as torecord identity authentication data and service transaction data between the satellite virtual trust areas. According to the method, the performance defects of a traditional satellite network can beovercome, and better safety performance can be obtained.

Description

technical field [0001] The invention relates to block chain and physical unclonable function application technology. More specifically, the present invention relates to a satellite management method based on blockchain and physically unclonable functions. Background technique [0002] With the rapid growth of the number of mobile users, providing users with safe and high-quality communication services anytime and anywhere has brought great challenges to wireless communications. Benefiting from the enhancement of on-board computing and signal processing capabilities, the Mobile Satellite Communication Network (MSNET) has become an important means of solving high-quality communications. The mobile satellite communication network has the characteristics of comprehensive coverage, long-distance communication, high transmission capacity, and gradually reducing dependence on the ground. While meeting basic satellite communication, it can also provide accurate and good services fo...
