Abstract
The present invention relates to an accredited certificate issuance system based on a block chain and a method using the same, and an accredited certificate authentication system based on a block chain and a method using the same, which disenable a leak of a personal key by autonomously generating, storing and managing the personal key by a random number generator mounted in a terminal in which it is impossible to install a function or an additional program for physically accessing; enable a public key for accredited certification to be stored in a block chain of electronic wallets mounted in block chain retention servers via a P2P network-based distribution database, not in a server of an accredited certificate authority (CA), and thus incur almost no costs for maintenance and for operating the established accredited certificate issuance system; and can perform an accredited certification process without ActiveX.
