 : Information provided by an Attester MUST NOT have been altered since it was created. This may be achieved via symmetric cryptography, e.g., using COSE Mac0 as in PSA TF-M profile ({{Section 5.2 of -psa-token}}), or asymmetric, such as a COSE Sign algorithm like ECDSA.
 
 Authentication:
-: The information provided by the Attester MUST be authentic. To do this, the Attester should authenticate itself to the Verifier. This can be done through implicit authentication using a digital signature over the Attestation Evidence, which does not require additional protocol steps, or by using a secure channel (see {{-uccs}}) including authentication.
