Abstract[English]
The invention relates to a method for providing attestations for a virtualized computing platform communicating with a relay server, the relay server being configured to generate a vector commitment from a random vector transmitted by the hypervisor of the virtualized computing platform and generate a zero-knowledge proof from this vector commitment, the proof being generated so as to prove that the hypervisor is in a valid configuration and that the link between the hypervisor and a virtual machine is valid, without disclosing the exact configuration thereof.[French]
Procédé de fourniture d'attestations pour une plateforme informatique virtualisée communiquant avec un serveur relais, le serveur relais étant configuré pour générer un engagement vectoriel à partir d'un vecteur aléatoire transmis par l'hyperviseur de la plateforme informatique virtualisée et générer une preuve à divulgation nulle de connaissance à partir de cet engagement vectoriel, ladite preuve étant générée de sorte à prouver que l'hyperviseur est dans une configuration valide ainsi que le lien entre l'hyperviseur et une machine virtuelle est valide, sans en divulguer la configuration exacte.
