Attestation
Attestation, in this context, refers to providing information about the device to other parties using a very simple, cryptographically secured token; this is part of PSA compliance. Attestation provides a device with the ability to sign an array of bytes with a device private key and return the result to the caller. There are several use cases, ranging from attestation of the device state to generating a key pair and proving that it has been generated inside a secure key store.
