Abstract

Conformément à certains aspects, les données sont reçues d'un programme d'appel. Un cryptogramme comprenant les données est généré, à l'aide d'un chiffrement de clé publique, d'une manière qui permet à seulement un ou plusieurs programmes cibles d'obtenir les données du cryptogramme. Conformément à un autre aspect, une chaîne de bits est reçue d'un programme d'appel. Un identifiant du programme d'appel est vérifié pour déterminer si le programme d'appel est autorisé à accéder aux données chiffrées dans le cryptogramme de la chaîne de bits. Les données sont chiffrées à l'aide d'un chiffrement de clé publique et retournée au programme d'appel seulement si le programme d'appel est autorisé à accéder aux données.
