Dispelling the Hype: When (not) to useBlockchain in IIoTWhen to use blockchain technology You need a shared database You need a database with multiple writers You have a situation with multiple non-trusting writers You do not want to rely on a trusted intermediary You desire interaction between transactions in the databaseAvoid using block chain technology If you lack any of the five above conditions “If trust and robustness aren’t an issue, there’s nothing ablockchain can do that a regular database cannot”, GideonGreenspan, CEO of Coin Sciences Ltd.

IIoT Security: NGAC for IIoTNGAC functional architecture: Multiple Policy Enforcement Points (PEP) Multiple Resource Access Points (RAP) At least one Policy Decision Point (PDP) One Policy Access Point (PAP) One Policy Information Point (PIP) An optional Event Processing Point (EPP)Ledger Tier use: Smart Contracts (SCs) used to effect changes to the distributedinformation and to enforce constraints on such changes Having multiple PDPs, and a distributed PIP, adds fault tolerance to theoperation of the distributed reference monitor (DRM) Smart contracts used to implement updates to the security policy thatmaintain consistency across the distributed PIPIoT Week, Aarhus, Denmark, June, 20th, 2019
