@par Protocol Description:
|
|
|
|
The EFI_BIS_PROTOCOL is used to check a digital signature of a data block against a digital
|
|
|
|
certificate for the purpose of an integrity and authorization check.
|
|
|
|
|
|
|
|
@param initialize
|
|
|
|
Initializes an application instance of the EFI_BIS protocol,
|
|
|
|
returning a handle for the application instance. Other functions in
|
|
|
|
the EFI_BIS protocol require a valid application instance
|
|
|
|
handle obtained from this function.
|
|
|
|
|
|
|
|
@param Shutdown
|
|
|
|
Ends the lifetime of an application instance of the EFI_BIS
|
|
|
|
protocol, invalidating its application instance handle. The
|
|
|
|
application instance handle may no longer be used in other
|
|
|
|
functions in the EFI_BIS protocol.
|
|
|
|
|
|
|
|
@param Free
|
|
|
|
Frees memory structures allocated and returned by other
|
|
|
|
functions in the EFI_BIS protocol.
|
|
|
|
|
|
|
|
@param GetBootObjectAuthorizationCertificate
|
|
|
|
Retrieves the current digital certificate (if any) used by the
|
|
|
|
EFI_BIS protocol as the source of authorization for verifying
|
|
|
|
boot objects and altering configuration parameters.
|
|
|
|
|
|
|
|
@param GetBootObjectAuthorizationCheckFlag
|
|
|
|
Retrieves the current setting of the authorization check flag that
|
|
|
|
indicates whether or not authorization checks are required for
|
|
|
|
boot objects.
|
|
|
|
|
|
|
|
@param GetBootObjectAuthorizationUpdateToken
|
|
|
|
Retrieves an uninterpreted token whose value gets included and
|
|
|
|
signed in a subsequent request to alter the configuration
|
|
|
|
parameters, to protect against attempts to replay such a request.
|
|
|
|
|
|
|
|
@param GetSignatureInfo
|
|
|
|
Retrieves information about the digital signature algorithms
|
|
|
|
supported and the identity of the installed authorization
|
|
|
|
certificate, if any.
|
|
|
|
|
|
|
|
@param UpdateBootObjectAuthorization
|
|
|
|
Requests that the configuration parameters be altered by
|
|
|
|
installing or removing an authorization certificate or changing the
|
|
|
|
setting of the check flag.
|
|
|
|
|
|
|
|
@param VerifyBootObject
|
|
|
|
Verifies a boot object according to the supplied digital signature
|
|
|
|
and the current authorization certificate and check flag setting.
|
|
|
|
|
|
|
|
@param VerifyObjectWithCredential
|
|
|
|
Verifies a data object according to a supplied digital signature
|
|
|
|
and a supplied digital certificate.
