  • Verified boot and key rotation
    Patent number: 10992482
    Abstract: Methods, systems, and apparatus, including computer-readable media, for verified boot and key rotation. In some implementations, a device extracts a public key from a secure data storage area of the device. The device extracts a first certificate for an intermediate key and a second certificate for a signing key, the first certificate and the second certificate being extracted from a system image. The device verifies a signature of the first certificate using the public key. After verifying the signature of the first certificate, the device verifies the second certificate using a public key in the first certificate. In response to verifying the second certificate, the device loads the system image during a boot process of the device.
