Decentralized Authentication Simulation by using Reputation over Blockchain

Description

A simulation software created for the masters thesis with the title of

"Introducing a Decentralized Framework to Provide Authentication on IoT devices"

This application is an implementation of the proposed framework on the dissertation. The application can run as three different roles and with predefined parameters. Besides that, it contains a property file to change the configurations of the framework as you want. Each role can make different interactions with transactions. The intention is to simulate the blockchain by using a central database which follows a distributed reputation scheme.

Run the application to see all the parameters needed to pass.

Features

Some of the features of this application are:

Blockchain simulation by using a central DB
Asynchronized transactions on Blockchain
Public Key cryptography implementation
Verifying transactions by Digital Signatures
Calculating Proof-of-Work by using Leading Zeros
Distributed Reputation Scheme

Requirements

This application was developed and tested with the following specifications:

Java JDK 8
MySQL 5.6.26
Maven 4
Apache Commons

Installation

To install this application first you need to make your environment ready as specified in requirements section. Then clone this repository and run the following on command line:

git clone [repo_url]
mvn install
mysql -u [username] -p [database_name] < dec_auth_sim.sql
Change the configuration file accordingly ("src/main/resources/config.properties")

TODO: Improvements in the future

Add Spring to use the Dependency Injection
Add Hibernate for easier and better SQL Queries
Add AutoCreate Schema if does not exists functionality
