Latest Patents

Ramsdale holds a patent for the "Validation of iPXE scripts using owner certificates and ownership vouchers." This patent describes techniques and architecture for validating and verifying iPXE scripts prior to execution during the booting process. The process involves a trusted iPXE script making a request to a network server for the ownership voucher and owner certificate of the network device right after the UEFI/BIOS stage of the booting process. The ownership voucher and owner certificate are stored in a trusted platform module (TPM) on the network device. The retrieved owner certificate is validated by the ownership voucher, allowing the owner certificate to be used for validating iPXE scripts. Once validated, the iPXE scripts can be executed, continuing the booting process to the kernel loading step and the application loading step. During subsequent booting processes, the ownership voucher and owner certificate can be retrieved from the TPM.
