  • Publication number: 20240378295
    Abstract: An embodiment of the invention provides a data authentication device. The data authentication device may include a main memory, a backup memory, a platform control hub (PCH) and an embedded controller (EC). The main memory may be configured to store data. The backup memory may be configured to back up the data stored in the main memory. The PCH is coupled to the main memory and generates a write command to write a first data image to the main memory, wherein the first data image comprises updated data and a digital signature. The EC is coupled to the main memory, the backup memory and the PCH and obtains the first data image from the PCH. When the EC detects a write command, the EC may perform an authentication for the updated data based on the first data image or a second data image corresponding to the first data image.

  • Patent number: 11321258
    Abstract: An integrated circuit includes a specific pin, an output circuit, a voltage detector, and a controller. The output circuit is coupled to the specific pin. The voltage detector obtains a detection voltage value from the specific pin. In response to an alert request, the controller provides a control signal to the output circuit based on the detection voltage value, so as to selectively control the output circuit to transmit the alert signal to the specific pin. When the control signal instructs the integrated circuit to operate in a blocking mode, the output circuit blocks the alert signal from being transmitted to the specific pin. When the control signal instructs the integrated circuit to operate in a transmission mode, the output circuit transmits the alert signal to the specific pin.
