The iPhone does grant real security, it just requires the user to choose an encryption key that isn&#x27;t trivially brute forced. (And depending on the circumstances, forego use of the fingerprint reader.)<p>If the dead attacker had a twelve character passphrase, any amount of help from Apple would be utterly useless. Apple could write all the back-doors they liked but if the content is encrypted and the key is unknown, brute forcing is the only option.<p>The addition of the secure enclave makes it <i>potentially</i> infeasible to extract the UID so that the brute forcing could be performed on a powerful supercomputer. It depends how well the enclave has been hardened against firmware changes. Can the enclave receive a seamless firmware update while in a locked state? Can the enclave firmware be rewritten to output the UID to the main CPU? We don&#x27;t know.
