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 29):
The method of  claim 28 , wherein the steps of S 520  to S 580  includes:\n a step S 511  of the certificate-managing server, if the revoking signal is determined as generated at the certificate-managing server, instructing its transaction-processing engine to receive the transaction information for user verification, to generate the transaction information for revocation, and to sign the generated transaction information for revocation using a private key of the sender which is the certificate-managing server, to thereby transmit the signed transaction information for revocation to the blockchain nodes; and \n a step S 512  of the blockchain nodes storing the signed transaction information for revocation in the blockchain, to thereby complete the revocation of the public certificate.
