Ejemplos de token de atestación

La directiva de atestación se usa para procesar la evidencia de atestación y determinar si Azure Attestation emite un token de atestación. La generación de tokens de atestación se puede controlar con directivas personalizadas. Aquí se muestran algunos ejemplos de una token de atestación.

Algunas de las notificaciones usadas aquí se consideran en desuso, pero se admiten por completo. Se recomienda que todas las herramientas y códigos futuros usen los nombres de notificaciones que no estén en desuso. Para obtener más información, consulte las notificaciones emitidas por Azure Attestation.

Las notificaciones siguientes solo aparecen en el token de atestación generado para las plataformas de servidor basadas en procesadores escalables de Intel® Xeon®. Las notificaciones no aparecen si el enclave de SGX no se ha configurado con Separación de claves y compatibilidad con uso compartido.
