Arm expects that there will be 1 trillion connected devices by 2035, and these devices will all require a secure identity, enabling stakeholders to build trust—for example, enabling service providers to trust devices and authenticate devices , providing value-added services and releasing security updates when needed.
SIM cards have long provided a stable, trusted and proven identity security authentication mechanism for mobile phones and other connected devices. However, once a traditional SIM card is installed on a device, its properties cannot be changed and the mobile network operator (MNO) needs to be changed by means of physical access. In the future smart cities, villages, and industries undergoing digital transformation, we will have billions of connected devices, many of which will benefit from cellular network connections, but physical change SIM cards are not scalable, or even Too feasible.
In addition to the problem of physical entity access, the integration of this technology into smaller IoT devices to achieve large-scale, low-cost deployments will also face cost and size barriers. In order to ensure the transparency and interoperability of device identity management with the development of the Internet of Things, it is imperative to simplify the technology and improve cost efficiency. Advances in the size of embedded SIM (eSIM) and more recently integrated SIM (iSIM) are critical to providing secure identity authentication for cellular IoT devices.
Today, Arm will adopt new technologies that comply with the GSMA embedded SIM specification to provide device manufacturers and service providers with secure identity authentication for cellular IoT applications. Combined with a more secure on-chip secure area architecture such as Arm CryptoIsland, MCU, cellular modem and SIM authentication can be integrated into a single IoT system-on-a-chip (SoC), significantly reducing equipment costs.
• Arm Kigen OS provides a scalable, small footprint, GSMA-compliant software stack that fully integrates SIM functionality into IoT SoC designs.
• Arm Kigen Remote Configuration Server solution enables flexible modular design for easy integration with MNO and IoT platforms.
By 2025, as many as 4.4 billion IoT devices are expected to be connected to the cellular Internet of Things (Machina, 2017). The solution enables SIM authentication (and its associated security level) at a lower price while enabling more flexible deployment. This step is critical for operators, chip providers and module vendors to recognize the potential of cellular IoT and has received strong support from key ecosystem players including BT, SoftBank and Sprint.
Secure identity authentication is a key principle of the Arm Platform Security Architecture (PSA), the first common industry framework we announced at the end of 2017 to build secure networking devices. The PSA is a robust system architecture that covers both hardware and firmware, while incorporating these common security principles into a range of system requirements and interface specifications. The Kigen product line follows the PSA listed safety and immutable identification principles.
This technology will enable a new level of cellular IoT integration while providing new services, business models and revenue streams to all cellular IoT ecosystem participants.
