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 Technologies Alexandros Papageorgiou, INLECOM Systems, UK CHARIOT-VESSEDIA Workshop 9 May 2019, Dublin, Ireland CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 1
01 DLT Introduction & Benefits 02 Refence IoT Scenario PRESENTATION AGENDA 03 Approach to Securing IoT Network 04 Conclusion and Final Notes CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 2
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 4
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 5
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 7
Approach to Securing IoT Network Legend Data Aggregators Wireless Wired IoT Gateways IoT Sensors CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 9
Approach to Securing IoT Network Certificate Authority Identity Certificate CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 10
Approach to Securing IoT Network Compromised Authority CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 11
Approach to Securing IoT Network Power = 3 Power = 1.5 Power = 1 CHARIOT VESSEDIA Workshop, 9 May 2019, Dublin, Ireland 12
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 13
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.
