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 2):
The system of  claim 1 , wherein the issuance-requesting server includes a DB part;\n wherein the DB part stores the user identification information on the user who operates the user device, and has an identification information DB which stores all the pieces of user identification information corresponding to all the pieces of personal information; wherein the user device transmits the personal information to the issuance-requesting server to thereby request the issuance, wherein the issuance-requesting server, if information corresponding to the personal information is determined as present in the identification information DB, generates and transmits a transmission-requesting signal for the public key to the user device, wherein the user device transmits the transmission-requesting signal to the information security device, wherein the information security device, if the transmission-requesting signal is received, instructs the encryption engine to generate the public key using the private key stored in the memory, and transmits the public key to the user device, and wherein the user device transmits the public key to the issuance-requesting server.
