Moreover, pre-boot information may be internally stored in the CPU and may be retrieved upon a reset or power-on event in order to verify a signed boot information on the basis of the internal symmetric encryption key. Furthermore, the BIOS information may be efficiently updated by generating a signature using the internal encryption key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer system comprising a secure boot mechanism on the basis of symmetric key encryption","description":"A CPU, a computer system and a secure boot mechanism are provided in which a symmetric encryption key may be incorporated into a non-volatile memory area of the CPU core, thereby substantially avoidin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8464037","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.
