  • SECURED COMMUNICATION PROTOCOL LAYER FOR AUTHENTICATED HARDWARE DATA ACCESS
    Publication number: 20240020364
    Abstract: A disclosed method installs an I/O trap protocol to provide an authentication callback function for handling I/O trap events. I/O trap events may include write operations accessing any of one or more identified I/O addresses. An I/O trap event may be registered with the authentication callback function for each of one or more identified I/O addresses. Original values of data may be stored in a memory resource. Any occurrences of an I/O trap event triggers the authentication callback function to perform I/O trap operations. The I/O trap operations may include determining whether the I/O trap event is associated with an approved driver and, if not, restoring data stored at the identified I/O address to an original value. Installing the I/O trap protocol may include installing the I/O trap protocol during a system management mode (SMM) phase of a UEFI boot sequence.
