Creating trust in devices begins early in the design process and figures in aspects of manufacturing, service and maintenance processes through and up to their eventual end of life. Many devices store and process valuable information such as service subscriptions, health records, credit card and banking information, and similar data on behalf of their owners that must be protected to prevent against threats and misuse against their rightful owners. Deeply embedded security has never been more critical.
Embedding a hardware root of trust enables chip manufacturers and their OEM/ODM customers to create a strong cryptographic device identity that is permanently bound to that unique device instance. This identity may be used by the manufacturer on the owner’s behalf to provide secure maintenance or enable new features and services over the entire lifecycle of the device. A critical element of retaining an owner’s trust in device is that the device’s integrity can be measured and demonstrated. This trust can then be extended to the network and other connected devices.
The DesignWare tRoot HSMs with Root of Trust provide designers with a Trusted Execution Environment (TEE) that protects sensitive information and data processing within their system-on-chips (SoCs) and communication with external entities.
There are two tRoot HSM product families:
- The flexible tRoot Fx HSMs with programmable root of trust include fully programmable and highly configurable solutions that enable designers to tune the HSM to their exact requirements.
- The pre-built tRoot Vx HSMs offer a defined security boundary for a complete, drop-in security solution.
