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 5):
The method of  claim 1 , wherein, the certificate-managing server includes a DB part having a keyword DB, a transaction-processing engine, and a hashing engine;\n wherein the transaction-processing engine stores the user identification information in the keyword DB, and creates transaction information for storing the public key, wherein the transaction information include the public key, and a transaction ID for storing the public key used as a key value for searching the transaction information for storing the public key, wherein the hashing engine acquires user-verifying hash information for authentication calculated by hashing the transaction ID for storing the public key and the user identification information included in the transaction-requesting signal, and wherein the transaction-processing engine (i) transmits the transaction information for storing the public key to blockchain nodes, (ii) stores the transaction ID for storing the public key in the keyword DB, (iii) creates (iii-1) transaction information for user verification including the user-verifying hash information for authentication and (iii-2) a transaction ID for user verification to be used as a key value for searching the transaction information for user verification, (iv) transmits the transaction information for user verification to the blockchain nodes, and (v) stores and manages the transaction ID for user verification in the keyword DB.
