Detailed Description

Implementation of EnclaveAssertionVerifier that verifiers assertions generated by the Intel ECDSA quoting enclave.

These assertions attest, to a remote party, properties about both an enclave's code as well as the Intel platform properties.

Constructor & Destructor Documentation

◆ SgxIntelEcdsaQeRemoteAssertionVerifier() [1/2]

asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::SgxIntelEcdsaQeRemoteAssertionVerifier ( )

Constructs a new SgxIntelEcdsaQeAssertionVerifier that generates assertions suitable for use with EKEP.

◆ SgxIntelEcdsaQeRemoteAssertionVerifier() [2/2]

asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::SgxIntelEcdsaQeRemoteAssertionVerifier ( std::unique_ptr< AdditionalAuthenticatedDataGenerator > aad_generator )

explicit

Constructs a new SgxIntelEcdsaQeAssertionVerifier that uses aad_generator to generate the expected additional authenticated data to be matched with quotes.

Member Function Documentation

◆ AuthorityType()

std::string asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::AuthorityType ( ) const

overridevirtual

Gets the type of this assertion authority.

Returns: The type of this authority.

Implements asylo::EnclaveAssertionAuthority.

◆ CanVerify()

StatusOr<bool> asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::CanVerify ( const AssertionOffer & offer ) const

overridevirtual

Indicates whether the assertion offered in offer can be verified by this verifier.

Returns: True if the offer can be verified, and false if no errors occurred during the operation but offer cannot be fulfilled. Returns a non-OK Status if the verifier is not initialized or if an internal error occurs while attempting the operation.

Implements asylo::EnclaveAssertionVerifier.

◆ CreateAssertionRequest()

Status asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::CreateAssertionRequest ( AssertionRequest * request ) const

overridevirtual

Creates an assertion request compatible with this verifier's identity type and authority type and places the result in request.

Parameters

[out] request The generated request.

Returns: A Status indicating whether the request was created. Returns a non-OK Status if this verifier is not initialized or if an internal error occurs while attempting the operation.

Implements asylo::EnclaveAssertionVerifier.

◆ IdentityType()

EnclaveIdentityType asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::IdentityType ( ) const

overridevirtual

Gets the enclave identity type handled by this assertion authority.

Returns: The identity type handled by this authority.

Implements asylo::EnclaveAssertionAuthority.

◆ Initialize()

Status asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::Initialize ( const std::string & config )

overridevirtual

Initializes this assertion authority using the provided config.

Parameters

config A config with which to initialize this authority.

Returns: A Status indicating whether initialization succeeded.

Implements asylo::EnclaveAssertionAuthority.

◆ IsInitialized()

bool asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::IsInitialized ( ) const

overridevirtual

Indicates whether this assertion authority has been initialized successfully via a call to Initialize().

Returns: True if this authority is initialized.

Implements asylo::EnclaveAssertionAuthority.

◆ Verify()

Status asylo::SgxIntelEcdsaQeRemoteAssertionVerifier::Verify	(	const std::string &	user_data,
		const Assertion &	assertion,
		EnclaveIdentity *	peer_identity
	)		const

overridevirtual

Verifies an assertion that is compatible with this verifier's identity type and authority type.

The verification operation verifies that the assertion's identity claim is valid, and also checks that the assertion is bound to user_data. If verification succeeds, returns an OK Status and extracts the peer's identity into peer_identity. The caller cannot make any assumptions about the contents of peer_identity if verification fails.

Parameters

	user_data	User-provided binding data.
	assertion	An assertion to verify.
[out]	peer_identity	The identity extracted from the assertion.

Returns: A Status indicating whether the assertion was verified successfully. Returns a non-OK Status if this verifier is not initialized or if an internal error occurs while attempting the operation.

Implements asylo::EnclaveAssertionVerifier.
