Title (EN) DUAL-SIGNED EXECUTABLE IMAGES FOR CUSTOMER-PROVIDED INTEGRITY
(FR) IMAGES EXÉCUTABLES À DOUBLE SIGNATURE POUR INTÉGRITÉ FOURNIE PAR LE CLIENT
Abstract:
(EN) In one embodiment, a computing device receives an image that has been signed with a first key, wherein the image includes a first computational value associated with it. A second computational value associated with the image is determined and the image is signed with a second key to produce a signed image that includes both the first and second computational values. Prior to loading the dual-signed image, the computing device attempts to authenticate the dual-signed image using both the first and second computational values, and, if successful, loads and installs the dual-signed image.
(FR) Un mode de réalisation de l'invention concerne un dispositif informatique qui reçoit une image qui a été signée avec une première clé. L'image contient une première valeur de calcul qui lui est associée. Une deuxième valeur de calcul associée à l'image est déterminée et l'image est signée avec une deuxième clé pour produire une image signée qui contient à la fois les première et deuxième valeurs de calcul. Avant le chargement de l'image à double signature, le dispositif informatique essaie d'authentifier l'image à double signature en utilisant à la fois les première et deuxième valeurs de calcul et, en cas de réussite, charge et installe l'image à double signature.
