IS415：Course Design In System Software (File Vault)

This project implements an encrypted file vault, by function overloading for system calls.

Install

Precondition

Make sure your node.js version is v16.13.1, and you can update your node version through this tutorial.

$ sudo apt install nodejs npm
$ node -v
v16.13.1

Next, you need to initialize the db.

$ sudo apt install mysql-server
$ sudo apt install libmysqlclient-dev

# check the status of mysql
$ sudo apt install net-tools
$ sudo netstat -tap | grep mysql

# set the password of the user “root”
$ sudo mysql
> update mysql.user set authentication_string=PASSWORD("123456"), plugin="mysql_native_password" where user="root";
> flush privileges;
> exit;

# restart the mysql server
$ sudo /etc/init.d/mysql restart

# initialize the db
$ mysql -u root -p
> create database test;
> use test;
> create table user (name varchar(100) not null, password varchar(100) not null);
> exit;

Finally, you need to initialize the vault directory.

$ sudo mkdir /vault
$ sudo chmod 777 /vault

Kernel

$ cd kernel
$ make
$ sudo insmod VaultModule.ko

GUI

We use electron to build the user-side program.

$ cd gui
$ npm install

If you have encountered some installation problems caused by network connections, try following steps to complete the installation progress :)

$ cd node_modules/electron
$ node install.js

Next, compile the netlink into a dynamic link library.

$ cd netlink
$ gcc -c -fPIC -o netlink.o netlink.c
$ gcc -shared -o libnetlink.so netlink.o

The last step, run the project!

$ cd ..
$ npm start

Enjoy it!
