As we observe the world in which we live, and in particular the electronic devices that surround us, we cannot help but be amazed at how quickly technology has evolved and how this pace of evolution continues to accelerate. The functionality of connected devices is rapidly increasing, and, accordingly, the value of the information stored on these devices, or information accessible through these devices is also rapidly rising. Because these value-rich devices are often connected to a network, cybercrime and cyber security concerns are also today’s front page news.

In this discussion I will address securing devices for connected and Internet of Things (IoT) systems. We’ll also look at how virtualization can be leveraged to enable consolidation and reliability of connected devices and at how ARM TrustZone can be utilized to address categories of security threats. Throughout the supply chain spanning semiconductor vendors, software developers, and system integrators, there are three interrelated topics that are consistently discussed: (1) IoT connectivity, (2) a move to ARM-based System on Chip (SoC) architectures, and (3) security.
