Tailoring Onion Routing to the Internet of Things: Security and Privacy in Untrusted Environments

| August 15, 2019

In trusted environments, e.g., smart homes, the establishment of security for IoT devices is well understood. However, the emergence of other private and industrial mobile use cases, such as pet monitoring  or container and parcel tracking, involve IoT devices that operate in untrusted networks, e.g., using public Wi-Fi or ad-hoc networks for Internet access. Inevitably, new risks come up in these environments. First, the relationship between communicating parties reveals private or secret routines [6] and, combined with location data, eases theft of valuable goods. Second, IoT devices in untrusted networks lack either a globally routable IP address or traditional defense mechanisms such as firewalls and intrusion detection systems.

Nokia adds 5G to worldwide IoT network, lets carriers test new sensors

Article | March 17, 2020

Nokia may be best known for cellular phones, but in recent years the Finnish company has focused on networking hardware — the radios and infrastructure that connect cellular devices to the internet. Today, Nokia announced that it’s augmenting its Worldwide Internet of Things Network Grid (WING) with new 5G capabilities, enabling cellular carriers to offer global-scale 5G IoT services to customers without building out their own networks. While that’s a lot of jargon to absorb at once, the gist is that carriers like AT&T and Verizon want to offer business customers the ability to connect small IoT sensors to the internet but don’t necessarily want to spend the money to build the cellular infrastructure the sensors need to communicate. So Nokia offers WING as a global IoT infrastructure, partnering with carriers to sell access on a pay-as-you-go basis.

What Is CBRS and How Does It Help IoT?

Article | February 26, 2020

The Internet of Things continues to grow fueled by applications that solve problems for enterprise customers. One of the biggest barriers to IoT solutions in enterprise settings is reliable and low-cost wireless connectivity. Where Wi-Fi, Bluetooth, LoRa, Zigbee and others have tried to solve the problem before, CBRS (Citizens Broadband Radio Service) is posed to offer a viable alternative for enterprise IoT connectivity. Specific to the United States, Citizen’s Broadband Radio Service (CBRS) is a piece of the radio spectrum between 3550 – 3700 MHz. This is a valuable area of the spectrum because it allows good propagation (ability to penetrate walls and go medium distances) with the benefits of higher bandwidth services, such as LTE and 5G.

Zigbee vs. Bluetooth: Choosing the Right Protocol for Your IoT Application

Article | March 5, 2020

Both Zigbee® and Bluetooth® wireless protocols are widely used for local communications in Internet of Things (IoT) applications, and there are some trade-offs to review in choosing the right one for your application. Each protocol has unique strengths that guide which solution to implement when designing a new network. In certain situations, one protocol will be a better fit than the other, though sometimes the right solution is to implement both together to take advantage of their combined strengths, as we will discuss in this article. To better understand these IoT protocol options, let's take a look at the advantages and limitations of Zigbee, followed by the same for three different "flavors" of Bluetooth: Classic, BLE, and BT Mesh. This will help explain the trade-offs and show some use cases for each, so that you can choose the optimal protocol for your IoT application - be it a smart city, industrial IoT, digital signage or other connected technology use case.

Connected Fleet Management: Why a Unified Network is Key

Article | April 15, 2020

As consumer demands evolve, fleet managers are turning to IoT to deliver products faster and more efficiently. The progress being made in edge computing represents the full potential of IoT: the power of data on the move. However, operating on the edge also reveals some of IoT’s greatest challenges: maintaining network security as the number of endpoints multiplies; rethinking traditional business models as industries become increasingly interdependent; and, perhaps most importantly, establishing a seamless, reliable network across borders, cultures, and regulatory environments.
