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 15):
The system of  claim 14 , wherein the authentication-requesting server includes a DB part and a hashing engine;\n wherein the DB part has an identification information DB which stores all pieces of user identification information related to an issuance of the public certificate, wherein the authentication-requesting server acquires from the identification information DB the user identification information, in response to a request for authentication from the user device, and transmits the user identification information to the certificate-managing server, wherein the hashing engine (i) acquires user-identifying hash information for comparison by hashing the user identification information, and (ii) acquires user-verifying hash information for comparison by hashing both the user-identifying hash information for comparison and the transaction ID for storing the public key, and wherein the authentication-requesting server determines whether a hash value of the user-verifying hash information for authentication corresponds to a hash value of the user-verifying hash information for comparison.
