Blockchain-based Secure Communication Model or Protecting Sensor Network Data Integrity in Smart Agriculture Systems

Abstract

The reliability of decision-making depends on ensuring data integrity when data comes from sensor networks in smart agriculture systems. The research develops a blockchain-supported secure communication model which protects against weaknesses in agricultural IoT systems. Distributed ledger architecture along with smart contract validation protocols forms the basis of the model for authenticating sensor data. Testing conducted in several agricultural settings confirmed data verification reached 99.7% accuracy and the detection of tampering achieved a success rate of 98.2% while authentication methods operated with 43% faster speed than conventional techniques. All simulated security breach attempts failed to penetrate the system which operated effectively in different field conditions. A scalable solution now provides agricultural data protection capabilities which allow farmers and agribusinesses to trust their sensor data for advanced crop management efficiency and resource planning and yield assessment.
