Abstract
Dans certains modes de réalisation, les données sont reçues d'un programme d'appel. Un cryptogramme contenant les données est généré à l'aide d'une clé de chiffrement publique de façon à ce que seulement un ou plusieurs programmes cibles soient capables d'obtenir les données à partir du cryptogramme. Dans un autre mode de réalisation, une chaîne binaire est reçue d'un programme d'appel. Un identificateur du programme d'appel est vérifié pour déterminer s'il a la permission d'accéder aux données chiffrées dans le cryptogramme de la chaîne binaire. Les données sont déchiffrées à l'aide d'une clé de déchiffrement publique et renvoyées au programme d'appel seulement s'il a la permission d'accéder aux données.
