Abstract
Ce procédé (PGBD) de gestion d’une base de données de clés publiques est mis en œuvre par un dispositif serveur. Il comporte : - une étape (E20) d’obtention d’une clé d’indexation (CIX-CL1), ladite clé d’indexation étant obtenue en mettant au moins en œuvre une fonction de hachage cryptographique appliquée au moins à au moins une clé publique ; et - une étape (E40) d’enregistrement de ladite au moins une clé publique dans un enregistrement de ladite base de données indexé par ladite clé d’indexation (CIX-CL1) si ladite clé d’indexation est unique. La clé d’indexation (CIX-CL1) peut être distribuée à un tiers pour lui permettre d’obtenir et d’authentifier la clé publique. Figure 3This method (PGBD) of managing a public key database is implemented by a server device. It comprises: a step (E20) of obtaining an indexing key (CIX-CL1), said indexing key being obtained by implementing at least one cryptographic hash function applied to at least one public key; and - a step (E40) of recording said at least one public key in a record of said database indexed by said indexing key (CIX-CL1) if said indexing key is unique. The indexing key (CIX-CL1) can be distributed to a third party to enable them to obtain and authenticate the public key. Figure 3
