1results about How to "Improve data transmission security" patented technology

The application relates to the technical field of Internet of Things communication, and discloses a blockchain-based Internet of Things cross-network data security interaction method and system, which is characterized in that: based on the communication data of an Internet of Things sending end, the feature information of a shared Internet of Things communication sending end is used to establish a distributed communication data sharing ledger of the Internet of Things sending end, so that a high-reliability communication data tamper-proof system of the Internet of Things sending end is scientifically established based on blockchain technology; through an Internet of Things gateway, the communication data of an Internet of Things receiving end is dynamically acquired, and the feature information of a shared Internet of Things communication receiving end is combined with data processing to establish a distributed communication data sharing ledger of the Internet of Things receiving end, so that a high-reliability communication data tamper-proof system from the Internet of Things sending end to the receiving end is scientifically established based on blockchain technology, and the data transmission security of Internet of Things cross-network communication is improved.
