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

Common Challenges


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



Blockchain IoT Registry API

• Creation of a user (registrant)

• Registration of IOT devices

• Registration of specifications of IOT devices

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

Trusted Asset Lifecycle Phases

1. Provisioning2. Tracing

- Chain of Custody- Usage Tracing- External Events- Structural Changes

3. Decommissioning


End State: Internet Scale Trust

A multi-provider blockchain network with open standards, global interoperability built on anchors of trust
