[webauthn] Requirements for security of MDC, DPK and attestation (#1808)

keikoit has just created a new issue for https://github.com/w3c/webauthn:

== Requirements for security of MDC, DPK and attestation ==
We (some RPs in Japan) think, for high assurance services, the minimum requirements are either

1. (MDC with no attestation) + (DPK with attestation), or
2. (MDC with attestation) + (DPK with no attestation required)

To achieve what RPs need to know about detecting an access from a new device, attestation can be hardware-protected provenance type or integrity-check type provided by platform.
Integrity-check type attestation, e.g.,SafetyNet, Apple attestation, can be userd with DPK by RPs to securely identify an MDC access from a new device IF the platform protects private keys securely.
