Application: Apparatuses and methods with secure configuration update (Patent ID: US20230395110A1)
The patent filed by NXP Semiconductors NV describes a method and apparatus for securely updating an integrated circuit to prevent unauthorized modifications. The system involves an application-specific circuit receiving an indication for an update while a nonvolatile memory is write-protected and access to an external network is enabled. A reset-and-boot circuit then resets and boots the application circuit with access to the network disabled, allowing for the installation of the update. A recovery circuit facilitates the installation of downloaded updates and allows for the retrieval of updates from the external network, ensuring secure and controlled updates to the integrated circuit.
The apparatus includes various components such as a system-on-chip (SoC) circuit, Internet of Things (IoT) devices, and communication circuitry to enable network communication. The method involves storing a programmed configuration in a nonvolatile memory circuit, operating the application-specific circuit with the existing configuration, and executing a reset-and-boot circuit to update the configuration based on downloaded updates. The patent also covers scenarios where the nonvolatile memory includes external and internal flash memory circuits, with provisions for write-protection, write-lock modes, and resilient recovery images. Overall, the patent outlines a comprehensive system for securely updating integrated circuits while ensuring protection against unauthorized modifications.
