Using Zero Knowledge Proof algorithms for authentication in services that run on blockchain
Data Flow Diagram -
Steps to run the code:
- Open MYSQL Workbench 8.0 or higher, connect as root user with the password given in the code and see that there tables with the names node1, node2, ... , node7
- Run all the verifiers one after the other: Node1_verifier_v2, Node2_verifier_v2, ... , Node7_verifier_v2
- This means that all the nodes have their "consensus-entities" in an always-on and connected mode
- Then run Node1_PowerRaiser_v2, Node3_PowerRaiser_v2, Node6_Authenticator_v2 and Node7_Authenticator_v2
- These are the container servers that will help in either the registration or login
- Then, run Node5_v2 with the login function call commented, and the registration function call uncommented if you want to register a user. During this time, there will be a block mined with the Zero Knowledge Proof intermediate variables as parameters of transactions. You will get a message indicating if the registration and the block mining was successful
- Do otherwise if you want to login as an existing user. There won't be any blocks mined for login (for now at least)
- If the whole system returns a true value, you'll be succcessfully logged in. Otherwise, it is bubye!
