Abstract:

Utilizing blockchain technology, Secure and Efficient Distributed Network Provenance for IoT provides a reliable and dependable answer to the pressing problems of data integrity and provenance in IoT networks. In this piece, we discuss the need for SEDNP in the IoT and suggest a blockchain-based architecture to implement it. We present a unified provenance query model and design a provenance digest strategy that 1) allows compact (constant size) on-blockchain digests of provenance data and a multilevel index regardless of provenance data volume and 2) verifies the on-blockchain digests to guarantee the correctness and integrity of provenance query results. Additionally, we integrate a verifiable computation (VC) framework with a blockchain testing network and run extensive tests with this setup. In order to prove that SEDNP may be put to practical use, experimental data are offered as performance benchmarks.
