MULTI-NODE AUTHENTICATION METHOD AND APPARATUS BASED ON BLOCK CHAIN

The authentication method of a block chain authentication module includes: receiving an authentication preparation request(S301); configuring a channel and generating a channel key allocated to the channel(S302); generating a block including an authentication comparison data(S303), the block further including a block key allocated to the block; commonly transmitting the channel key and the block key, and dividing and transmitting the authentication comparison data(S304); transmitting an authentication preparation completion message including the channel key and the block key(S305); receiving an authentication request message including the channel key, the block key, and authentication target data(S306); dividing and transmitting the authentication target data(S307); receiving a result of comparing the divided and transmitted authentication comparison data with the divided and transmitted authentication target(S308); and determining whether the authentication of the terminal succeeds(S309).
