Detailed Description

An implementation of the EnclaveAssertionGenerator interface for null assertions.

NullAssertionGenerator generates assertions based on assertion requests from a NullAssertionVerifier. The generated assertions have no cryptographic bindings and are trivially verifiable by a NullAssertionVerifier.

Constructor & Destructor Documentation

NullAssertionGenerator()

asylo::NullAssertionGenerator::NullAssertionGenerator

(

)

Constructs an uninitialized NullAssertionGenerator.

The generator can be initialized via a call to Initialize().

Member Function Documentation

AuthorityType()

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

overridevirtual

Gets the type of this assertion authority.

Returns

The type of this authority.

Implements asylo::EnclaveAssertionAuthority.

CanGenerate()

StatusOr<bool> asylo::NullAssertionGenerator::CanGenerate ( const AssertionRequest &  request ) const

overridevirtual

Indicates whether the assertion requested in request can be generated by this generator.

Parameters

request

A request to be fulfilled.

Returns

True if the assertion specified in request can be generated, and false if no errors occur during the operation but request cannot be fulfilled. Returns a non-OK Status if this generator is not yet initialized or if an internal error occurs while attempting the operation.

Implements asylo::EnclaveAssertionGenerator.

CreateAssertionOffer()

Status asylo::NullAssertionGenerator::CreateAssertionOffer ( AssertionOffer *  offer ) const

overridevirtual

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

Parameters

[out]

offer

The generated offer.

Returns

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

Implements asylo::EnclaveAssertionGenerator.

Generate()

Status asylo::NullAssertionGenerator::Generate ( const std::string &  user_data, const AssertionRequest &  request, Assertion *  assertion  ) const

overridevirtual

Generates an assertion that satisfies the given request, if request is compatible with this generator's identity type and authority type.

The caller cannot make any assumptions about the contents of assertion if generation fails.

Parameters

	user_data	User-provided binding data.
	request	A request to fulfill.
[out]	assertion	The generated assertion.

Returns

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

Implements asylo::EnclaveAssertionGenerator.

IdentityType()

EnclaveIdentityType asylo::NullAssertionGenerator::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::NullAssertionGenerator::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::NullAssertionGenerator::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.
