Abstract
An issuing device is configured to: respond to a challenge request by transmitting a challenge; and respond to a certification request including a public key and ownership information thereof by issuing a digital certificate certifying the ownership information. The ownership information includes counterparty identity information relating to a ledger of a distributed database. The digital certificate is issued if it is successfully verified that a valid response to the challenge has been posted to the ledger of the distributed database and is associated therein with the counterparty identity information of the certification request. The digital certificate facilitates proofing that an owner of a public key is a given counterparty to a blockchain ledger. Also, a corresponding requesting device and corresponding methods and computer program products for issuing and requesting a digital certificate are disclosed.
