### 1. What is verifiedBootKey
* This is the public key used to sign the boot image (boot/recovery/system, etc.).
* It is stored in the firmware and acts as the root of trust when verifying system integrity.
* The device manufacturer “burns” it into the Trusted Execution Environment (TEE) or processor fuses (eFuse/OTP).
* If the key doesn’t match the expected one, the system considers the boot process unsafe.
In simple terms:
verifiedBootKey = who signed the firmware (root of trust).
---
### 2. What is verifiedBootHash (or boothash)
* This is a hash (SHA256, etc.) of the boot partition contents (or a set of partitions, depending on AVB).
* It is calculated at boot time and compared with the reference value from the manifest.
* If the hash is different → the partition has been modified (e.g., custom kernel or ramdisk).
In simple terms:
verifiedBootHash = what exactly was loaded (the actual boot state).
---
### 3. Connection and difference
* BootKey determines whether we trust *the signer of the firmware*.
* BootHash determines whether *the boot partition itself has been modified*.
Analogy:
* Key (verifiedBootKey) = the manufacturer’s official stamp.
* Hash (verifiedBootHash) = the fingerprint of the specific paper that has the stamp.

### 4. In the context of Key Attestation
In Android Key Attestation the TEE signs a report that contains:
*
*
* Together they allow external services to verify that the device is booting in a trusted and unmodified environment.
