- Abstract
- A method and an apparatus for device security verification utilizing a virtual trusted computing base are provided. The validity of a key for decryption is verified by a secure memory loader running on a processor of a device after booting of the device which is a computing device, and if the key is valid, encrypted firmware stored in a memory of the device is decrypted using the key to verify the confidentiality of the firmware. Then, the security memory loader verifies the authentication and integrity of the firmware by comparing a signature value generated for the decrypted firmware with an existing signature value.
