A Blockchain-Based Metxod of Tracting Internet of Things Terminal Privacy Information
The information security of Internet of Things equipment terminals involves user privacy.In order to improve the recognition and security of Internet of Things terminal information,a method of tracing the privacy information based on blockchain is proposed.U-sing the joint access control method of blockchain and Internet of Things,the distributed storage model of Internet of Things terminal pri-vacy information data is established,and the identity authentication and data encryption steganography of Internet of Things terminal blockchain privacy information are realized through the joint block authentication and encryption method of attributes.Based on the secur-ity fusion analysis of the whole blockchain,the three-layer combined protocol control method of application service layer,intermediate protocol layer and basic network layer is adopted.This method realize the chain storage optimization design of the Internet of Things ter-minal privacy information blockchain,extracts the key information of the Internet of Things terminal privacy information,adopts the iden-tity-based cryptographic architecture to protect the Internet of Things terminal privacy information and secure identity authentication,transmits the key to users safely,and uses bilinear fitting tracking to trace the Internet of Things terminal information.The test results show that this method has good encryption and strong privacy protection control ability,and improves the distributed storage ability and data protection ability of blockchain.
