  • Patent number: 11783043
    Abstract: A method is provided for authenticating firmware images in an embedded system. The method may include loading and executing a trusted firmware using a pre-existing Secure Boot on a baseboard management controller (BMC). The BMC is configured as a master for an embedded system including System On Chips (SOCs) configured as slaves, out-of-band interfaces between the BMC and the SOCs, and flash storages in electrical communication with the SOCs. The method may also include pushing or uploading, by the BMC, a secure SOC firmware image to one of the SOCs using one of the out-of-band interfaces, verifying a digital signature extracted from the SOC firmware image by using a hash code calculated from the SOC firmware image and decrypted using a public key stored on the BMC and notifying a user about verification of the digital signature.

  • Publication number: 20230287959
    Abstract: A centrifugal pendulum device is provided having a weight carrier disc an opening and guide tracks arranged on a radially outer region thereof and including damper spring openings in a radially inner region thereof. A centrifugal weight is disposed displaceably on the weight carrier disc, with the centrifugal weight including two side elements that each include weight guide tracks, and spacing bolts arranged between the two side elements. At least one of the spacing bolts extends through the opening of the weight carrier disc, and the centrifugal weight is guided displaceably on the weight carrier disc by roller elements that run on the guide tracks and the weight guide tracks. In order to reduce weight and provide additional flexibility, the weight carrier disc comprises a first plate that includes the radially inner region that is connected to at least one second plate that includes the radially outer region.
