COMPUTER SYSTEM COMPRISING A SECURE BOOT MECHANISM ON THE BASIS OF SYMMETRIC KEY ENCRYPTION |
摘要 |
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 avoiding any tampering of the encryption key by external sources. 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.
