Blockchain-Enabled Secure Data Transmission Framework for Next-Generation Sensing Applications
Annotatsiya
Sensing systems of the next generation, such as smart cities, self-driving vehicles and industrial IoT, require a system of data transmission to be secure and efficient to permit integrity, confidentiality and trust. The traditional centralized security measures can be exploited with the single points of breakdown, data manipulation, and unauthorized access. In this paper, a data transmission system based on blockchain is suggested to offer secure data transmission through the combination of cryptographic hashing, digital signatures, and decentralized consensus to exchange immutable and verifiable sensing data. The architecture uses light edge gateways, which use lightweight blockchain nodes to reduce the latency with a high throughput. A mathematical model is created to determine transaction verification time, probability of data integrity and energy usage. Experimental simulations of Hyperledger Fabric have shown that the proposed framework minimizes the probability of data tampering by 94, throughput by 28, and latency by 17 per cent relative to non-blockchain base protocols. The outcomes prove that blockchain is effective in enabling next-generation sensing application with limited performance trade-offs.
