Method for preventing redundant data attack in a distributed cloud based on a blockchain

摘要

In the block chain-based distributed cloud attack response method according to the present invention, instead of one server in the block chain network, several servers form each node, and the nodes form one block chain-based cloud network, and all data is a method of ensuring authentication, non-repudiation, and integrity by configuring blocks in blocks and storing them in the blockchain. Instead of storing only one file uploaded by a user in the network, three copies of the file are stored in different nodes to ensure the stability of the file. characterized by increasing the
