Better messaging means security can grow with IoT

Stephen Lawson | June 18, 2014
The brake pedal in your car probably isn't attached to the brakes. But don't worry, the pedal knows how to tell the brakes that you've pressed it. And now there's a new way to secure the messages they send each other.

DDS Security has a multicast function that lets the sending device encrypt a message once and send it to multiple destinations at the same time, Barnett said.

RTI expects DDS Security to be adopted broadly across industries where DDS is used today, but it won't be an overnight change. In health care, energy and some manufacturing sectors, that might happen in less than five years, Barnett said. Other industries, such as automotive, may take longer because they're more fragmented. RTI's focus is on industrial IoT, not connected consumer devices.

There are other standard IoT messaging protocols, including MQTT (Message Queuing Telemetry Transport) and AMQP (Advanced Message Queuing Protocol), but at least a handful of these can and will coexist, VDC's Rommel said. IoT as a whole will have to grow even as it remains fragmented, because many industrial embedded systems stay in the field for 10 to 20 years without updates, he said. Meanwhile, peripherals and gateways can make disparate systems talk to each other. In fact, RTI itself makes such adapters.

"There can be a partial move toward standard technology, but it certainly won't be a complete one," Rommel said. "There'll be different bridges and Band-Aids to help make it happen."

Pricing for Connext DDS Secure starts at US$9,495 per developer for new customers and $2,000 per developer for current Connext DDS customers, with discounts for larger projects.
