A UEFI interceptor block (IB) I/O driver intercepts each block I/O command targeting block addresses on a storage device and identifies whether any of the target block addresses is encrypted. In response to identifying an encrypted block address among the target block addresses, the UEFI IB I/O driver forwards data associated with the encrypted block address to an encryption-decryption module to perform one of an encryption and a decryption of the data. Final handling of the block I/O command is performed using a block I/O driver chained to the UEFI IB I/O driver. Data associated with I/O commands targeting encrypted block addresses is first processed by the encryption-decryption module before final handling of the I/O command is performed by the block I/O driver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for intercept of UEFI block I/O protocol services for bios based hard drive encryption support","description":"An information handling system and method performs Unified Extensible Firmware Interface (UEFI) interception and pre-processing of data associated with block input/output (I/O) commands targeting encr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589156","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.
