METHOD FOR MANAGING A PUBLIC KEY DATABASE, METHOD FOR AUTHENTICATING PUBLIC KEYS, AND SERVER DEVICE AND CLIENT DEVICE IMPLEMENTING THESE METHODS

摘要

This method (PGBD) for managing a public key database is implemented by a server device. The method comprises: - a step (E20) of obtaining an index key (CIX-CL1), said index key being obtained by at least implementing a cryptographic hash function that is applied at least to at least one public key; and - a step (E40) of recording said at least one public key in a record in said database that is indexed by said index key (CIX-CL1) if said index key is unique. The index key (CIX-CL1) may be distributed to a third party in order to allow same to obtain and authenticate the public key.
