Abstract
Conformément à certains aspects, des données sont reçues d'un programme appelant. Un cryptoprogramme qui comprend les données est produit, au moyen d'un chiffre symétrique, de manière à ne permettre qu'à un ou plusieurs programmes cibles de pouvoir obtenir les données du cryptogramme. Conformément à d'autres aspects, une chaîne de bits est reçue d'un programme appelant. Un identifiant du programme appelant est vérifié pour déterminer si ce programme appelant est autorisé à accéder aux données chiffrées dans le cryptogramme de la chaîne de bits. L'intégrité des données est également vérifiée, et les données sont déchiffrées au moyen d'une clé symétrique. Les données sont retournées au programme appelant, seulement si le programme appelant est autorisé à accéder aux données, si l'intégrité des données donne une vérification concluante.
