The Internet of Things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies Then The Big Question is Security? Number of IoT Device Market Revenue Massive, right? IoT Network
- 3. What is Blockchain & How does it works? The Blockchain: Usefully, the blockchain is a distributed ledger, shared by untrusted participants, with strong guarantees about accuracy and consistency. Components of BC? Node Distributed Ledger Chain Consensus Mechanism Hash: 1z8f Previous Hash: 0000 Hash: 8bq1 Previous Hash: 1z8f Hash: 3h4q Previous Hash: 8bq1 yx7c Not right! Popular Blockchain Platform: Ethereum VeChain WaltonChain IOTA IoTex IoT Chain Here we used IOTA for some specific benefits!
- 4. SPEED(TPS): $0.01 Usability Scale No Needs of Mining/ NO FEES Support Micro Transaction It Scales! Motivation High speedTransaction Per second SECURITY: Highly Secure & Immutable The more txns are the more secure and efficient the tangle gets Why IOTA?
- 5. Workings of IOTA Unlike other Blockchain Network, IOTA uses: IOTA Stands for “Internet of Things Application” Tangle/ Directed Acyclic Graph(DAG) Provides faster Proof of Work (PoW) Performance. Needs few nodes to authenticate Transaction The Tangle The concept of IOTA is almost same as the Blockchain Network but the mechanism is differ.
- 6. Research Objectives We want to design a Smart Home Application where: Ensure security, confidentiality, integrity, and authentication of this Smart Home System Can control all the IoT via network(Blockchain) automatically Prevent all the possible attacks on the Smart Home Can control the system without central authority or server We want to integrate IOTA Distibuted Ledger in IoT based Smart Home
- 7. Background Study 1. “Towards an optimized blockchain for IoT” - Ali Dorri and Kanherel S and Jurdak Analyzed the interaction of IoT elements with Smart Home in BC and gives the basic concept of Smart Home. 2. “Emergency service for smart home system using Ethereum blockchain: system and architecture” – Thitinan Tantidham Thitinan Tantidham talks about the emergency service for a Smart home System (SHS) based on Ethereum blockchain with smart contract which gives 24/7 hours automatic service in any abnormal situation. 3. Advanced survey of blockchain for the Internet of Things smart home - AbuNaser, Maha and Alkhatib Maha AbuNaser explains how Blockchain can help to secure the data, transaction and describes the security analysis in IoT smart homes. 4. “Network-level security and privacy control for smart-home IoT devices” – Sivaraman, Vijay and Gharakheili 5. Internet of things (IoT) of smart home: privacy and security - Shouran, Zaied and Ashari, Ahmad and Priyambodo, Tri Shouran et al. presented the impact of various security attacks on smart home and evaluated their impact as a low, moderate, and high to appropriate solutions for their mitigation. Sivaraman et al. investigated security vulnerabilities in the smart home network and proposed solutions. ** We have reviewed more than 50 releted research paper

- 14. Conclusion In this paper, we proposed a Blockchain-based architecture for the smart home gateway environment and IoT. This architecture powerup the confidentiality, integrity, and authentication of the heterogeneous IoT and centralized gateways. We have successfully implemented IOTA Distributed Ledger in IoT based Smart Home
