A Blockchain-Based Hierarchical Authentication Scheme for Multiserver Architecture

Figure 1

A blockchain-based hierarchical multiserver authentication system in a school league. Each school has its own confidential servers and normal servers. These servers can identify the user’s identity with the help of the blockchain system, regardless of the school they come from. And the confidential server is only available to the teachers who have access to it, while the students do not have access to it.
