Abstract
A method for authenticating a specific user by using certificates including a specific certificate of the specific user based on a blockchain network is provided. The method includes steps of: an authentication-supporting server, (a) on condition that a transaction is stored in a distributed database on the blockchain network from when a previous anchoring condition is satisfied to when a current anchoring condition is satisfied, wherein the transaction includes a root hash value created by a Merkle tree operation to leaf nodes having hash values of the certificates and the certificates including public keys of users, root hash identification information, and a transaction ID for locating the transaction on the distributed database are stored in the authentication-supporting server as corresponding to the specific user, if authentication of the specific user is requested, confirming validity of the specific certificate; and (b) if the specific certificate is valid, authenticating the specific user.
