5G Iot Data Sharing Technology Based on Blockchain
In view of the problems such as access logs being tampered with in cloud server database and difficulty in tracing and tracing,this paper proposes a 5G iot data sharing scheme based on blockchain,which gives full play to the characteristics of blockchain anonymity,decentralization and immutable,and improves the security and privacy of shared data.The 5G iot data sharing framework based on blockchain is composed of data provision nodes,data need nodes,cloud servers,and blockchain servers,and realizes data sharing and ensures data security by registering legitimate nodes,updating node status,conducting data transactions,and building blocks.At the same time,an off-chain transaction mechanism based on the lightning network was introduced to further improve the transaction processing speed of the blockchain,achieving a balance between security and efficiency.
