Module attestation 

TDX attestion related shared types and functions

Structs

QuoteInputData

Input data to be included in a TDX attestation

Enums

QuoteContext

An indicator as to the context in which a quote is intended to be used

VerifyQuoteError

An error when verifying a quote

Constants

MEASUREMENT_VALUE_MOCK_QUOTE

The acceptable TDX measurement value for non-production chainspecs. This is the measurement given in mock quotes. Mock quotes have all zeros for each of the 5 48 bit measurement registers. The overall measurement is the Blake2b hash of these values. So this is the Blake2b hash of 5 * 48 zero bytes.

Traits

AttestationHandler

A trait for types which can handle attestation requests.

Functions

compute_quote_measurement

Create a measurement value by hashing together all measurement registers from quote data

verify_pck_certificate_chain

A mock version of verifying the PCK certificate chain. When generating mock quotes, we just put the encoded PCK in place of the certificate chain so this function just decodes it, checks it was used to sign the quote, and returns it
