Abstract
A communication method for the secure management of keys and identities of an Object manufactured by a Manufacturer having a Manufacturer key pair (Ksman, Kpman) and a client having a Client key pair (Ksclient, Kpclient), that is carried out at least partially on a decentralized blockchain database by generating by the Manufacturer two diversified symmetric keys from its key pair and from diversifiers, sharing keys with the object, publishing and recording the decentralized identifier (DID) in the database, wherein when a Client purchases the object from the Manufacturer, providing the identifier of the object DID by the Manufacturer, updating the blockchain, when the object is initially switched on, auto-enrolling by generating new symmetric keys, sending two new encrypted diversifiers to the client with the public client key, publishing and recording new encrypted diversifiers with the public client key in the blockchain.
