Japanese consumer electronics company Casio is using Trustronic’s TSP secured platform to protect health data on its latest smartwatch. Trustonic is a UK venture formed in 2012 by Arm and Gemalto.
Casio selected TSP to bring additional security and trust to its flagship wearable. The just-launched Casio Pro Trek Smart WSD-F21HR has features such as GPS, offline maps, heart rate and VO2 maximum measurement, designed for athletes and consumers who enjoy the outdoors.
The watch uses an optical sensor that measures heart rate by flashing an LED light into the wrist. This lets users measure the intensity of their exercise in real time.
The smartwatch market is set to be worth over $31bn by 2025, driven by consumer demand for new wearable features and advancements in sensors, processing power and connectivity. To meet these demands, safeguard its customers and brand, and support its application developer community, Casio is using Trustonic’s hardware-backed security to enable enhanced smartwatch features, functionality, speed and ease of use for outdoor adventurers. Trustonic is helping Casio to protect the sensitive tracking and biometric data that are now stored and transmitted by wearables.
“Wearables are rapidly gaining momentum, driven by consumer demand for cool new features and richer experiences,” said Ben Cade, CEO of Trustonic. “To future-proof smartwatches, deliver new functionality and safeguard the personal data captured, processed and transmitted by them, innovative OEMs like Casio are looking to the security best-practices of the smartphone ecosystem. Our TSP platform enables devices to be designed, developed and built on a proven foundation of hardware-backed trust. With our help, Casio is enabling end-users to go harder in search of something new.”
TSP is a proven security technology already deployed in two billion smart devices. It protects connected devices such as wearables, smartphones, automotive in-vehicle infotainment platforms and healthcare devices by delivering standards-based, hardware-backed security. It provides security-by-design from the silicon level up with no additional bill of materials for the OEM and has been optimised to meet the requirements of high-volume manufacturers such as Casio.
TSP uses Trustonic’s common criteria and GlobalPlatform-certified TEE trusted execution environment, which is enabling Casio to satisfy Google’s Keymaster and verified boot requirements and develop future-proof consumer smartwatches.
“Casio’s customers have active lifestyles and high expectations of wearable devices, and Trustonic is helping Casio to lead the charge in pursuit of new experiences,” said Cade. “Of course, meeting security requirements is essential, and our clients like Casio always put users’ privacy first, but integrating TSP is also about enabling application developers to build apps on a foundation of trust that help athletes to be more dynamic in their enjoyment of the great outdoors.”
The TEE is a secure area of the main processor in a smart phone or any connected device that ensures sensitive data are stored, processed and protected in an isolated, trusted environment. The TEE's ability to offer isolated safe execution of authorised security software, known as trusted applications, enables it to provide end-to-end security by enforcing protection, confidentiality, integrity and data access rights. The TEE offers a level of protection against software attacks, generated in the Rich OS environment. It assists in the control of access rights and houses sensitive applications, which need to be isolated from the Rich OS.
