CSEN 1001 Computer & Network Security Project

Project Description:

Guidelines 

This project should be done individually or in team of two. You can share ideas, consult the TA, and search online. However, all work done in this project must be done individually or by all team members.

The main aim of this project is to test your knowledge of the security concepts taught in this course.

Teams have to implement the Extra Required Deliverables for Teams in addition to the General Deliverables.

All external assets used from the internet must be credited and commented in your project.

Any plagiarism detected will be penalized with a zero.

You are free to use any programming language.

Description 

What is the main Idea? 

In this project, we will design a cryptocurrency similar to ScroogeCoin. A network of 100 users will simulate the transaction processes. Initially each user will have 10 ScroogCoins. As long as the system is running, a random transaction with random amount (within the range of amount the user has) will be created from User A to User B. The transaction is signed by the private-key of the sender. Scrooge get notified by every transaction. Scrooge verifies the signature before accumulating the transaction. Once Scrooge accumulates 10 transaction, he can form a block and attach it to the blockchain. You are allowed to use predefined hash and digital signature libraries. Mention which libraries you used. 

General Deliverables 

❖ A designated entity “Scrooge” publishes an append-only ledger that contains

all the history of transactions. ❖ The ledger is a blockchain, where each block contains transactions, its ID,

the hash of the block, and a hash pointer to the previous block. The final hash pointer is signed by Scrooge. ❖ A simulation of the network, with multiple users and the randomized process of making a transaction, making each transaction reach an arbitrary user. ❖ The design and implementation of the ledger based on the concept of the

blockchain (hash linked list). ❖ Upon detecting any transaction, scrooge verifies it by making sure the coin

really belongs to the owner and it has not been spent before. ❖ If verified, Scrooge adds the transaction to the blockchain. Double spending

can only happen before the transaction is published. ❖ For digital signature, use any of the technique described throughout the course.
