Spatial information network access control system and authentication method based on blockchain

Abstract

The invention provides a spatial information network access control system and authentication method based on a blockchain, the spatial information network access control system based on the blockchain comprises a ground blockchain module, an inter-satellite blockchain module and a client, wherein the ground blockchain module comprises ground stations and a gateway station; each ground station andthe gateway station are provided with a link; the inter-satellite blockchain module comprises a low-orbit satellite; and the client comprises each mobile user. The invention further provides a spatial information network access control authentication method based on the blockchain. The method comprises a related parameter initialization and registration process, an access authentication and authority management control process and a transfer process based on the blockchain. According to the invention, rapid authentication and access permission confirmation of the user equipment can be satisfied, the data integrity and security in the whole process are further enhanced by introducing the blockchain, the problem of single-point failure existing in network control NCC in an actual scene is solved, and access control and operation traceability functions are provided.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based spatial information network access control system and authentication method. Background technique [0002] The spatial information network makes it possible for any object to be connected to the Internet anywhere. Access authentication is the key to secure user access control, mainly to prevent illegal opponents from accessing secure network services. However, the communication environment of star sensors is very complex, which poses a challenging problem for designing secure and efficient authentication schemes. Blockchain can be viewed as a public, digital and distributed ledger built on a peer-to-peer network, which has been introduced and applied to many network scenarios. [0003] In a blockchain system, data generated by participating entities is published as transactions, and transactions are packaged into a block. Miners add data to the blockcha...

AI Technical Summary

Problems solved by technology

[0006] 1. The security of mutual authentication is not high enough

[0007] In the mutual authentication of this scheme, the information used is sent from both parties, and the further information verification can only ensure that the information has not been tampered with, and cannot guarantee that the node sending the information has not been maliciously forged

[0008] 2. The traceability provided is not strong

However, under this scheme, NCC, as the central organization, may be attacked or maliciously operated by operators, resulting in tampering or deletion of relevant logs

[0010] 3. Cannot provide fine-grained access control
