The fast-growing M2M market presents a series of wireless design challenges (part 1)

When selecting wireless modems, there’s a checklist of features to consider. We’ve presented those here.

The growth rate of machine-to-machine (M2M) connections now far exceeds new connections between people, and soon there will be many more machines than people connecting over cellular Industrial computer networks, as shown in the GSM Association forecast in Figure 1. These in-vehicle system include security systems, meters, robots, vending stations, asset trackers, and emergency call systems. The variety is growing by the day, as are the silent conversations between millions of machines exchanging data 24 hours a day, 7 days a week, with no human intervention.

At the same time, it’s becoming cheaper and easier to connect to fleet management the Internet and even mass produced computing devices are able to gather and process ever-larger volumes of data. The one potential bottleneck to greater M2M connectivity, the fact that all 4 billion+ IP version 4 (IPv4) addresses are already allocated, has been removed with the introduction of embedded system. This supports 2128 addresses, more than enough for every grain of sand on Earth to have its own address. It’s perhaps no surprise then that LTE, the fourth generation of mobile networks (4G), is designed to deliver services such as data, voice, and video over IPv6.

To join the M2M in-vehicle system revolution, all that’s needed is to embed machines with small, economical (wireless) modems. Where location, speed, or navigation information needs to be established, the machines also need a GPS or GNSS (Global Navigation Satellite System) receiver. Both industrial computers, with an antenna, can fit easily in a device smaller than a mobile phone. GNSS is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. It includes GPS (U.S.), GLONASS (Russia), Galileo (Europe), BeiDou (China), and other regional systems.

When thinking about how to equip an embedded system with communications capability, start by thinking about the needs of the application. Factors such as industrial computer longevity, geographical network coverage, or future-proofing to take account of future wireless network upgrades, are all important considerations. Here are some of the product features to consider when selecting wireless fleet management modems.

The case for security in Linux-based IoT devices (part 1)

Are you among the embedded system OEM and software consultant adding Internet connectivity and services into devices that were not originally intended to do so? If you are, then you know that by connecting these products to the Internet, customers are discovering new forms of revenue and, in some cases, entirely new business models. What’s more, they are able to make their current products both more valuable and cost-effective.

As we continue to see more Internet-connected devices, we must acknowledge that they will be vulnerable to attack, remotely disabled, or compromised in some other undesirable way – each scenario seriously threatening the entire underpinning of these new business models.

Consider the following example in the world of home automation. It is one of the biggest consumer applications for the Internet of Things (IoT), and potentially one of the most lucrative for attackers. What could a criminal do with information stored in what might be considered a rather harmless home-automation device like an IP-connected smart thermostat? Well, these devices are built to learn your habits. They are designed to recognize or “learn” when you are home and when you are away, so that they can optimize the industrial computer used to heat and cool your house. You can guess where I’m going with this. They’ll know your habits and track your routines – sensational fodder for someone thinking about stopping by uninvited.

Remember the case of the Samsung Smart TV? In order to be able to respond to voice commands, it constantly “listened” to your chatter, interpreted it, and then might even send it to “authorized” third parties. Yes, I am serious. The Smart TV was demonstrated to be hackable (what isn’t without lock down security) back in 2013. This is a perfect example demonstrating the need for multiple embedded system accessibility levels. In the in-vehicle system case, there was only one user account possible, and that user could access anything on the device[1][2].

Security through obscurity

In many past instances, product developers would rely on the fact that their in-vehicle system devices were too few and too uninteresting to hackers to attempt to exploit them. In other words, these devices were obscure – ostensibly unknown nodes on a network. Unfortunately, this strategy will no longer work. With what is expected to be billions of devices connected to the Internet in next five years (with tremendous variety of functionality), these once “no interest” devices will become quite tempting as targets for exploit.

To address how security by obscurity will no longer work, let me offer an example of how a website is being used to search for Internet connected devices: www.acrosser.com
