Abstract:
A method for verifying data integrity of a block device is provided. The method includes providing a secure world execution environment configured to monitor changes to data blocks of a block device, within the secure world execution environment, generating a hash for changed data blocks of the block device, and within the secure world execution environment, verifying and generating a cryptographic signature.
