I was asked to propose some text on local attestation.

While it may be the case that an asset must sometimes be secret from the user, it is not the case that the user should know nothing about the asset; the end user should be able to verify the authenticity and integrity of the asset. To enable this, local attestation can be used to prove integrity to the user. The user can then use that integrity check to verify authenticity, for example by checking against a signature or by verifying the expected integrity check using conventional web pki.

Thanks,
Brendan
