Beispiele für ein Nachweistoken

Mit einer Nachweisrichtlinie wird der Nachweisbeweis verarbeitet und festgelegt, ob Azure Attestation ein Nachweistoken ausstellt. Die Erstellung von Nachweistoken kann mit benutzerdefinierten Richtlinien gesteuert werden. Nachfolgend sehen Sie einige Beispiele für ein Nachweistoken.

Einige der hier verwendeten Ansprüche werden als veraltet eingestuft, werden jedoch vollständig unterstützt. Es wird empfohlen, dass der gesamte zukünftige Code und alle Tools die nicht veralteten Anspruchsnamen verwenden. Weitere Informationen finden Sie unter Von Azure Attestation ausgegebene Ansprüche.

Die nachstehenden Ansprüche erscheinen nur in dem Nachweistoken, das für die Serverplattformen mit Intel® Xeon® Scalable-Prozessoren erstellt wurde. Die Ansprüche werden nicht angezeigt, wenn die SGX-Enklave nicht mit Unterstützung für Schlüsseltrennung und -freigabe konfiguriert ist.
