IIC Connectivity Framework Document


• Provides a comprehensive treatment of IIoT connectivity

• A new connectivity reference architecture to provide for secure interoperability between applications in an IIoTsystem

• A new connectivity “stack” model focused on syntactic interoperability for the IIoT

• Detailed analysis of key IIoT connectivity technologies against this new stack model

– DDS, OPC UA, HTTP, OneM2M, MQTT, CoAP

• Download it here: http://www.iiconsortium.org/IICF.htm

– V1.0 released Feb 28, 2017

DDS: Open IIoT Standard

• Data Distribution Service (DDS) is an open industry standard for data-centric connectivity

• From OMG, the world’s largest systems software standards organization

– UML, DDS

– Industrial Internet Consortium (IIC)

• DDS is Open & Multi-Vendor– Open Standard & Open Source

– 12 implementations


Interoperability between source written

Security Boundaries

• System Boundary

• Network Transport

– Media access (layer 2)

– Network (layer 3) security

– Session/Endpoint (layer 4/5) security

• Data & Information flows



DDS: Data-Centric, Fine-Grained Security


• Per-Data-Topic Security– Control r,w access for each function– Ensures proper dataflow operation

• Complete Protection– Discovery authentication– Data-centric access control– Cryptography– Tagging & logging– Non-repudiation– Secure multicast– 100% standards compliant

Demanding Security Test of RTI’s Implementation

• The USS SECURE cybersecurity test bed is a collaboration between:

– The National Security Agency– Department of Defense Information

Assurance Range Quantico– Combat Systems Direction Activity

Dam Neck– NSWCDD– NSWC Carderock/Philadelphia– Office of Naval Research– Johns Hopkins University Applied

Physics Lab– Real Time Innovations, Inc.

• Objectives– Immunize against cyberattack and to

rapidly recover when impacted– Determine the best cyberdefense

technologies without impacting real time deadline scheduled performance

System Aspect Example User Approach Target

Standard

Software

Integration and

Autonomy

You are a software architect. You are building

a system or product line, and you control the

architecture. You critically need to integrate

components written by different programmers

or even entire teams.

A data centric approach will define the

interfaces, capture the dataflow, enable

module evolution, and enforce

interoperation between teams. This

approach also eases redundancy, fast

complex data flow, and selective data

filtering.

DDS

Device

Interchangeability

You are a device manufacturer, with the goal

of making devices that will sell into many

applications. The device offers services, such

as configure, start, stop, etc. You have no idea

how the device will eventually be used. Your

users are likely not software experts; they just

want to add or integrate the device into a

workcell.

A device-centric approach will allow the

device users to write generic software that

will interoperate with competitor’s devices.
