摘要: A method and system for enabling security attestation a computing device during return from an S4 sleep state. When the enters into state following successful boot up, log is appended to TPM tick count signed (with signature). awaken state, BIOS obtains verifies created previous boot. The CRTM maintains set of virtual PCRs references these against log. If values do not match, fails rebooted.
