Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for booting a computing device having an encrypted storage medium using full disk encryption, referred to as tamper-resistant boot. The system retrieves a kernel cache and a kernel cache digest from an unencrypted storage medium and verifies the authenticity of the kernel cache based on the credentials and the kernel cache digest. Initiation and execution of the operating system is performed if the kernel cache is authentic. In one embodiment, the system verifies the authenticity of a request to disable tamper-resistant booting by utilizing a password verifier and a password proof.
