A DLT-based Trust Framework for IoT Ecosystems

Dec 2018 - Jan 2023

Architecture and trust-reputation framework for IoT edge-cloud ecosystems using DLT and off-chain ML trust computation.

Problem Statement

  • IoT ecosystems lacked transparent trust management across edge, cloud, and stakeholder boundaries.
  • Centralized trust approaches introduced single points of failure.
  • Security, decentralization, and scalability trade-offs needed measurable evidence.

What I Led

  • Designed DLT-based architecture for decentralized IoT ecosystems with off-chain ML trust computation.
  • Built and evaluated trust reputation mechanisms across different consensus and deployment choices.
  • Ran simulation experiments to assess security, decentralization, and scalability impacts.

Deliverables

  • DLT architecture and off-chain trust workflow
  • ML-driven trust reputation model
  • Simulation and evaluation outputs
