Abstract:
The present invention relates to an accredited certificate issuance system based on a block chain and an accredited certificate issuance method based on block chain using the same, and an accredited certificate authentication system based on a block chain and an accredited certificate authentication method based on a block chain using the same, which disenable a leak of a personal key for accredited certification by autonomously generating, storing and managing the personal key for accredited certification by means of a random number generator mounted in a terminal in which it is impossible to install a function or an additional program for physically accessing and reading the inside of a system; enable a public key for accredited certification, which requires maintenance, to be stored and managed in a block chain of electronic wallets mounted in block chain retention servers via a peer-to-peer (P2P) network-based distribution database, not in a server operated by an accredited certificate authority (CA), and thus incur almost no costs for maintenance by, if hacking occurs, preventing occurrence of costs for establishing an accredited certificate issuance system having an advanced security system interworking therewith so as to maximally prevent hacking, and costs for operating and maintaining the established accredited certificate issuance system; and can perform an accredited certification process even if ActiveX is not established.

Claim (Index 17):
The method of  claim 16 , wherein, the transaction information for user verification includes transfer information, wherein the transfer information has (i) amount of a cost deposit corresponding to cost deposit information for revocation of the public certificate and (ii) a reserve cryptocurrency address for transfer of the cost deposit to a designated cryptocurrency address, if the cost deposit information and transaction information for user verification are stored in the blockchain of the blockchain nodes, and wherein the cost deposit is to be used for revoking the public certificate,\n wherein the transaction-processing engine of the certificate-managing server (i) acquires the reserve cryptocurrency address from the transfer information, (ii) generates a confirmation-requesting signal that requests whether the cost deposit corresponding to cryptocurrency amount loaded at the reserve cryptocurrency address is transferred, and (iii) transmits the confirmation-requesting signal to the blockchain nodes, wherein the blockchain nodes transmit to the certificate-managing server a notifying signal which represents whether the cost deposit, loaded at the reserve cryptocurrency address retrieved from the blockchain, is transferred by referring to the reserve cryptocurrency address included in the confirmation-requesting signal, and wherein the transaction-processing engine, if the cost deposit loaded at the reserve cryptocurrency address is determined as transferred by referring to the notifying signal, transmits a message representing a refusal of the authentication to the user device.
