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 22):
The method of  claim 14 , wherein, the information security device includes its encryption engine and its hashing engine;\n wherein the authentication-requesting server which includes a hashing engine of the authentication-requesting server and a decryption engine of the authentication-requesting server, (i) if a hash value of the user-verifying hash information for authentication included in the validity-confirming signal transmitted from the certificate-managing server corresponds to a hash value of the user-verifying hash information for comparison, confirms a protocol used for Internet communications by the user device, and (ii) if the confirmed protocol is determined as HTTPS, instructs its random number generator to generate random numbers and relays the random numbers to the information security device by way of the user device, wherein the information security device instructs its hashing engine to acquire random number hash information for authentication by hashing the random numbers, instructs its encryption engine to acquire encrypted random number hash information for authentication by encrypting the random numbers using the private key stored in the memory, and relays the encrypted random number hash information for authentication to the authentication-requesting server by way of the user device, and wherein the authentication-requesting server instructs the hashing engine of the authentication-requesting server to acquire random number hash information for comparison by hashing the random numbers transmitted to the information security device, instructs the decryption engine of the authentication-requesting server to acquire the random number hash information for comparison by decrypting the encrypted random number hash information for comparison using the public key, and confirms that a hash value of the acquired random number hash information for authentication corresponds to a hash value of the random number hash information for comparison, to thereby complete the authentication of the user.
