  • USING GLASS WEAVE MARKER STRUCTURE TO AUTHENTICATE PRINTED CIRCUIT BOARDS
    Publication number: 20210382967
    Abstract: An apparatus includes a printed circuit board (PCB) that includes a woven glass laminate layer. The woven glass laminate layer includes a plurality of glass bundles woven together, where a marker structure including at least one marker is defined within the woven glass laminate layer. A security chip is coupled with the PCB and includes memory that stores an authentication identifier of the PCB, where the authentication ID includes a representation of the marker structure.

  • Selectively connecting a port of an electrical device to components in the electrical device
    Patent number: 9990321
    Abstract: Techniques are presented herein to enable a port of an electrical device to be selectively connected to either a first component or a second component of the electrical device. The port is configured to physically interface with an external device. The first component and second component perform different functions. A signal directing circuit is coupled to the port, and is configured to selectively connect the port to one of the first and second components.

  • Attesting authenticity of infrastructure modules
    Patent number: 9680816
    Abstract: A user device is provided that includes an authentication application that runs on the user device. A calibration device is also provided that includes authentication algorithm configuration information and an authentication token. The user device is connected to the calibration device to receive the authentication algorithm configuration information and the authentication token. The user device then supplies to a target device to be authenticated an authentication request that includes the authentication token. The user device receives an authentication response from the target device. The user device then analyzes the authentication response with the authentication application based on the authentication algorithm configuration information to determine whether the target device is authenticated.
