Detailed Description

Defines an interface for assertion authorities that create assertion offers and generate assertions.

EnclaveAssertionGenerator cannot be instantiated; it is intended to be derived from by classes that implement the EnclaveAssertionGenerator interface for a particular identity type and authority type.

Derived classes of EnclaveAssertionGenerator must also implement virtual methods presented by EnclaveAssertionAuthority.

Member Function Documentation

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

pure virtual

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.

virtual Status asylo::EnclaveAssertionGenerator::CreateAssertionOffer ( AssertionOffer * offer ) const

pure virtual

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.

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

pure virtual

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

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.
