| Abstract: | Extensible Firmware Interface (EFI) is the firmware technology proposed to replace BIOS. It can overcome the disadvantages of BIOS and provide more powerful functions and better interactions than BIOS. The execution of EFI is independent from the traditional operating system and it can control hardware of the system directly, which is the security threat to the system. The EFI security mechanism based on on-chip system was proposed to solve this problem. The security mechanism was designed based on the hardware resources on chips to provide security protection to EFI firmware. The analysis of the experimental results showed that the EFI security mechanism based on on-chip system could provide well protection to the EFI firmware. |
