jm4c/sirs-remotedocs

[University Project] A cloud based collaborative office application that allows documents to be shared over a network in a secure fashion.

RemoteDocs

Platform

The project is cross-platform. We tested it on Windows 10 64-bit and Linux 64-bit, but it should also run on OS X.

The only required dependency is the Java Development Kit 8.

Setup instructions

To build the project, run

./gradlew build

Then, start the server with

./gradlew :rdocs-server:run

and the client(s) with

./gradlew :rdocs-client:run

Client usage

The server address may be configures in rdocs-client/src/main/resources/client.properties (the default is localhost).

First, register a new user by clicking register and filling in the form.

Then, login with the user you just created and create a new document by clicking "New".

Give a title to the document, type in some text and click "Save", then "Close". You can reopen this document by selecting it and clicking "Open".

Go back to the login window by clicking "Logout" and register a new user. Login with this new user, create a new document and share it with the first user by clicking "Share" and then dragging the name of the user you want to share it with to the right pane and clicking "Save".

Login again with the first user, and notice the the shared document is now accessible to you.

When you open a shared document, you can see who is the owner (creator) of the document, and also see who made the last edit and when.

Demonstration

sirs-remotedocs's Issues

Improving GUI

Permission Revogation

Client's GUI

Last document editor must be known

Ability to store and get documents from server

Integrity verification of documents from server

Adding Read/Write permissions

Protect server from rogue clients

Due to its nature, RMI is vulnerable to custom malicious clients.
This issue is aimed to prevent those clients from manipulating or obtaining sensible information from the server.

Allow users to share documents

Document integrity must be preserved

Last editor must make sure he was the last user to edit the document (user from #5)

User not owner can steal owner's document

By keeping the document open and saving it after its old key is revoked, the user can steal the document. Keeping its owner out due to different secret key.
