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 24):
The method of  claim 23 , after the step of S 330 , further comprising:\n a step S 340  of the certificate-managing server instructing its transaction-processing engine to acquire a reserve cryptocurrency address for revocation of the public certificate from transfer information on a cost deposit included in the transaction information for user verification, creating a revocation-confirming signal which requests information on whether the cost deposit corresponding to amount of cryptocurrency loaded at the acquired reserve cryptocurrency address is transferred, and transmitting the revocation-confirming signal to the blockchain nodes; a step S 350  of the blockchain nodes transmitting to the certificate-managing server a notifying signal for revocation which informs whether the cost deposit loaded at the reserve cryptocurrency address is transferred, wherein the cost deposit is retrieved from the blockchain by referring to the reserve cryptocurrency address included in the revocation-confirming signal; a step S 360  of the certificate-managing server instructing its transaction-processing engine to confirm whether the cost deposit is transferred, by referring to the notifying signal; and a step S 361  of the certificate-managing server, if the cost deposit is determined as transferred, transmitting a message representing a refusal of the authentication to the user device.
