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 43):
The method of  claim 39 , wherein the steps of S 720  to S 750  includes:\n a step S 760  of the authentication-requesting server, if the protocol is determined as HTTPS, instructing its random number generator to acquire random numbers and relay the random numbers to the information security device by way of the user device; \n a step S 770  of the information security device instructing its hashing engine to acquire random number hash information for authentication by hashing the random numbers; \n a step S 780  of the information security device instructing its encryption engine to acquire encrypted random number hash information for authentication by using the private key stored in the memory, and relaying the encrypted random number hash information for authentication to the authentication-requesting server by way of the user device; \n a step S 790  of the authentication-requesting server instructing its hashing engine to hash the random numbers transmitted to the information security device to acquire random number hash information for comparison, instructing its decryption engine to decrypt the encrypted random number hash information for authentication by using the public key to acquire the random number hash information for authentication, and confirming if a hash value of the 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.
