  • Publication number: 20230246827
    Abstract: A management controller of a computer platform, determines whether an ownership history of management firmware for the management controller represents multiple owners. The management controller includes a set of one-time programmable elements that represent a first secret. The management controller manages use of the first secret based on the ownership history. The management includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, generating, by the management controller, a second secret to replace the first secret. The management further includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, storing, by the management controller, the second secret in a non-volatile memory and generating, by the management controller, cryptographic keys based on the second secret.

  • Patent number: 6654816
    Abstract: A communication interface system including a computer and a handheld device that communicate with each other via respective communication ports. The computer communication port is a serial port or an infrared transceivers conveniently located on the front bezel of the computer. In serial embodiments, the computer executes the appropriate driver and interface applications to enable transfer of information to the handheld device. In infrared embodiments, the computer includes a microcontroller, an I2C bus and memory, where the microcontroller implements infrared communication protocol. Alternatively, the computer may further include a management processor that either replaces or cooperates with the microcontroller. Auxiliary power may enable handheld communications when the computer is shut down. The handheld device interfaces with the computer communication port to retrieve and display the status information.
