Introduction EFI Boot Process The architecture of EFI Trust chain in EFI Trusted boot process of EFI TPM TPM Software Stack Attestation Problem
EFI?◦ Extensible Firmware Interface
Introduction (1/2)
BIOS Vs EFI◦ 바이오스가 하는일을 포함한 EFI -> 완전한 대체◦ 부팅속도◦ VGA 의존성 X 네트워크나 직렬라인으로부팅 가능◦ PreOS -> 드라이버인식 , 제어 ,cd, 파일복사 , 인터넷 ,마우스 , 쉘 ,GUI, 다국어 ( 한국어 )◦ 한계용량 극복 (Globally Unuque Identifier->GPT)◦ 운영체제 손상시 유용◦ C 언어로작성 -> 확장성◦ 다양한 플랫폼지원
