I don’t have visibility into
what is actually deployed
How can I ensure I’m running authentic
hardware and software?
Our vendors are required to provide
proof of secure development
practices
Procurement purchases hardware and software from
3rd parties, I’m assuming they are
approved

How Does BlockchainEnhance IoT Security?
• Helps build trust across the entire ecosystem across the supply chain from source to destination
• Pushes transparency as a first class citizen from supply chain, through logistics, and into operation
• Transaction/Event history is immutable

• Creation of a user (registrant)
• Registration of IOT devices
• Registration of specifications of IOT devices

Blockchain
BC Middleware
BC Network
Asset Layer▪ Examples: Truck, Train, Machine▪ Includes local and remote communication and
processing (on asset, fog)
IoT Cloud Layer▪ Asset connectivity & FOTA▪ Asset-related data and event management▪ Enterprise Application Integration
▪ Asset-related ledger entries
▪ Peer-to-Peer Middleware for management of BCs
▪ Network of compute nodes for BC

Asset-Access Protocols▪ Examples: TR69
IoT Cloud Protocols▪ Examples: MQTT
Blockchain Protocols
▪ Blockchain access, e.g. create new ledger entry
▪ Internal synchronization protocols
▪ Network protocols
On-Asset Protocols and Standards▪ E.g. TPM

4: Direct
Examples▪ 1a: IoT Cloud manages all asset data, selectively
writes critical data / events to BC▪ 1b: Cloud reads other asset`s data for validation,
e.g. for pairing of two assets▪ 2a: Track & Trace beacons send critical event to
gateway (e.g. via BLE), gateway forwards event to IoT Cloud, data is evaluated and stored in BC
▪ 4a: On-asset intelligence is executing BC logic and communication directly
