  • FAST REPOWERING USING CRYPTOGRAPHICALLY PROTECTED IDENTITY
    Publication number: 20250267002
    Abstract: A computing device connected to a power source via a combined power/data connection obtains an authentication request from the power source. The authentication request includes a freshness mechanism provided by the power source. The computing device signs an authentication response with a private key associated with a verified identity stored on the computing device. The authentication response includes the freshness mechanism. The computing device provides the authentication response to the power source, and receives power from the power source.
    Type: Application

  • DELIVERING SECURED POWER TO DEVICES
    Publication number: 20240388321
    Abstract: A power source that supplies power to authorized computing devices generates a query requesting the power usage of the computing devices over a predetermined time period. Each computing device receives the query and provides a response with an indication of the measured or estimated power usage during the predetermined time period. The power source adds up the power usage of each authorized computing device to determine a difference between the reported power usage and the power supplied to the authorized computing devices. The power source may mitigate any discrepancy by cutting off power to ports that are providing more power than is being reported as consumed by the authorized computing devices.
