For example, a cryptographic processor of a PCIe endpoint (such as a peripheral) may take a measurement (e.g., computing a hash value) of a code object on the device prior to executing the code object. This measurement may be placed in a register that is accessible to another component, such as a host operating system across a PCIe bus for interrogation. The host operating system may utilize an interconnect protocol, such as a PCIe protocol to access the measurement. These measurements may be consumed by a Trusted Platform Manager or other components of a host system that may verify the measurements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Exposing cryptographic measurements of peripheral component interconnect express (PCIe) device controller firmware","description":"Examples disclosed herein include are computing device hardware components, computing devices, systems, machine-readable mediums, and interconnect protocols that provide for code object measurement of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11522679","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
