In most Internet of Things (IoT) deployments, it’s good practice to authenticate anyone trying to access your device – typically through the Ethernet, WiFi, or other network protocol. But there’s a more subtle, and dangerous, way to get into your device: through a JTAG debug port. If someone gains physical access, he can create much more havoc because JTAG takes you to the low-level heart of a board or chip, where an expert hacker can take complete low-level control of the system – even replacing firmware with a rogue code.
In this contributed article for Embedded Computing Design, Digi’s Mike Rohrmoser explains the pluses and minuses of the use of Secure JTAG keys. Regardless of the approach you choose, Digi TrustFence™ security framework includes tools for manufacturing and maintenance, including Secure JTAG.
The zero-emission taxicab of the future will soon be on the streets of London – and Digi is playing a key role in making it happen. That’s because Frazer-Nash, the electric-car pioneer founded in 1922, has selected Digi’s ConnectCore 6 system-on-module to create a complete digital experience for driver instrumentation and touchscreen passenger infotainment inside its range-extended electric vehicle (REEV) Metrocabs. The ConnectCore 6 will also enable wireless connectivity to in-cab Internet, GPS navigation, and revenue-producing interactive displays.
The ConnectCore 6 is less than 2 inches square and includes all the power and connectivity you would expect from a PC, including a cellular adapter, 1080p graphics, Wi-Fi and Bluetooth, and up to 64GB of flash memory. The decision to utilize ConnectCore 6 was a change for Frazer-Nash, which traditionally develops all technologies in-house. In fact, the ConnectCore 6 is the only component in the Frazer-Nash Metrocab that was not designed and created by the company itself.
In this new Frazer-Nash “cab of the future,” drivers can monitor the cab’s key systems as well as optimize routes, fuel, and battery efficiency. What’s more, Digi offers secure remote management and web services capabilities through the scalable Digi Device Cloud™ so Frazer-Nash can monitor all of its cabs remotely and deploy updates over cellular networks.
Frazer-Nash has been in the forefront of electric powertrain development and designs and builds all of its own components. By using the ConnectCore 6, Frazer-Nash reduced costs and accelerated its time-to-market while offering new services and deliver a connected cab. The Metrocab is just one example of the incredible development opportunities for Digi customers and partners, brining computing power to new classes of innovative applications.

With the rapid growth of the Internet of Things, devices have become more vulnerable in recent years. Even with highly publicized security breaches (medical devices, web cams, vehicles, building automation equipment, etc.), it seems like security is still on the lower end of awareness and focus. And for those device manufacturers who are security-minded, implementation is not trivial.
Mike Rohrmoser, Digi’s Director of Product Management for Embedded Systems, spoke with Embedded Computing Design at NXP FTF 2016 about concerns surrounding connected devices. He emphasized that security requirements will change over time, so it’s imperative that device manufacturers make sure their products have a chance to support those changes.
Listen to the full interview to hear Mike’s thoughts on the state of connected device security and how Digi is addressing these deficiencies with a secure software framework and security architecture called Digi TrustFence™.
When you’re working for a major petrochemical company, inventory control isn’t merely a financial matter. That’s because a slow, undetected leak of a dangerous chemical substance can ultimately lead to significant safety concerns, and environmental/regulatory issues that can cost millions of dollars.
A major metro’s DPW team might be responsible for ensuring thousands of streets are operational on a 24×7 basis. Outages translate into lapses in public safety and unnecessary taxpayer expense. But how can they keep tabs on all of those fixtures?
Unfortunately, for organizations like these – and thousands of others facing the same dilemmas – the only feasible recourse has been to put technicians and repair teams on the road, logging thousands of miles each year to remote sites to manually check simple metrics like air quality, tank levels, pipeline pressures, valve statuses, light fixtures, and more. It’s a cost and headache that they’re eager to avoid – but the data is too important to avoid or ignore. In fact, the more difficult the data is to capture, the more valuable it often is.
Remote-sensor monitoring through wireless networks is the obvious – and long-sought – alternative, but too many barriers have prevented wide-scale adoption. Chief among these roadblocks: power consumption. Solar-powered wireless gateways are still not cost-feasible for industrial applications. Battery-powered cellular devices are another option, but until recently the costs of carriers’ rigid consumer-focused data plans (and the expense of the devices themselves) made them suitable for only a small subset of applications. Low-power WiFi networks and internal batteries can provide some coverage, but they require RF and network engineers to design, install, and maintain – expertise that is in high demand.
The Tide Is Turning
Fortunately, we’re seeing important changes that are making low- or no-power remote monitoring easy and cost-effective. First, cellular operators are recognizing that $30-50/mo. consumer data plans are a non-starter in the industrial space. Some carriers are now offering data plans of as little as 250 KB and compelling configurations and bundles that have driven prices down to $1-3/mo. High-volume customers are even seeing sub-$1 pricing.
Device costs have also plunged. Cellular gateways are now less than $20 for 2G and 3G modules. Similar dynamics are likely in the LTE space soon. And as M2M-friendly LTE CAT standards take hold in the coming years, we’ll see lower device costs, lower operating costs, and longer battery life – all with no need for a local wireless network to carry backhaul traffic.
Ultimately, it means we’re now able to deploy the small-footprint, no/low-power remote-sensor network that skips the truck rolls, cuts the costs, and increases visibility across the company’s entire asset portfolio. The new Digi Connect Sensor battery-powered cellular gateway lets companies and agencies finally deploy a no-infrastructure remote monitoring solution in virtually any harsh or remote environment.
Here’s more about the features of the Digi Connect Sensor:
Flexible power sources – Use a long-lasting (two to three years), non-rechargeable battery, power-saving sleep mode, and the option to draw power external sources (including solar) while using the internal battery as a backup.
