  1. CHARIOT-VESSEDIA Workshop “THE ROAD AHEAD FOR A COGNITIVE COMPUTING PLATFORM SUPPORTING A UNIFIED APPROACH TOWARDS PRIVACY, SECURITY AND SAFETY (PSS) OF IOT SYSTEMS” Blockchain and Distributed Ledger TechnologiesAlexandros Papageorgiou, INLECOM Systems, UK CHARIOT-VESSEDIA Workshop 9 May 2019, Dublin, Ireland CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  3. 1 – DLT Introduction & Benefits

  4. DLT Introduction & Benefits DLT: • Rapid propagation of information in a multi-party network • Distributed and synchronous at all times • Utilizes consensus mechanisms for synchronism • Data exchanged is not necessarily valid Blockchain: • A type of data structure that supplements DLT • Data are packaged to blocks that form a digital chain • Cryptographic & algorithmic methods are used for immutability and identification of actors CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  5. DLT Introduction & Benefits Potential Benefits: • Establishment of a trustless network of verifiable information exchange • Full immutable record of all actions within the network • Operation of traditionally centralized procedures in a distributed manner • Combination of multiple technology stacks under a single umbrella Potential Negatives: • Heavily misunderstood technology • Primarily associated with cryptocurrencies • Might possess costly operational overhead in situations it is not suited for CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  6. 2 - Reference IoT Scenario

  7. Reference IoT Scenario Use Case: Manufacturing Plant • Industry 4.0 stage with the usage of IoT • Predictive maintenance by data analytics and machine learning • Reduced operational cost due to properly allocated resources for maintenance • Increased revenue due to higher efficacy of manufacturing tools • Increased customer satisfaction as a result of faster demand fulfillment times • Reduced risk thanks to stricter operational compliancy • Correct Operation? Bona Fide Data? Malicious Devices? • All the above can lead to the exact opposite of the aforementioned benefits CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  8. 3 – Approach to Securing IoT Network

  9. Approach to Securing IoT Network Legend Data Aggregators Wireless Wired IoT Gateways IoT Sensors CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  10. Approach to Securing IoT Network Certificate Authority Identity Certificate CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  11. Approach to Securing IoT Network Compromised Authority CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  12. Approach to Securing IoT Network Power = 3 Power = 1.5 Power = 1 CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  13. Approach to Securing IoT Network Technologies Used: • Distributed Database • Asymmetric Cryptography • Symmetric Cryptography • Public Key Identification System • Blockchain technology encompasses all the above technologies under a single umbrella • + an immutable record history enabling full post-incident historical analysis CHARIOT – VESSEDIA Workshop, 9 May 2019, Dublin, Ireland

  14. 4 – Conclusion and Final Notes

  15. Conclusion and Final Notes What is blockchain: • Not a magical one-for-all solution • Capable of seamlessly integrating multiple technologies under a single solution • Effective if applied correctly • Easily extensible, maintainable & more robust Bibliography: • Sadeghi, Ahmad-Reza, Christian Wachsmann, and Michael Waidner.
