DeskCon Connection Security
2First of all, I’m not a Security Expert, I just use the well known Encryption and Security standards. So if you find any flaws in how I implemented that stuff, please tell me.
Basically I use self-signed Certificates with a TLSv1.2 SSL Connection. During the “pair”-Process, Desktop and mobile Device exchange their X509v3 Certificate and print out the Fingerprints (sha256), so that the User can verify their Identity. If the User says they match, the Certificates will be stored.
The Certificates are generated from a 2048-bit RSA Key-pair and signed with SHA256 Algorithm.
The SSL Connection is actually over TLSv1,TLSv1.1 or TLSv1.2 depending on your Android Version (TLSv1.2 is supported in Android 4.1 and up) and the OpenSSL Library Version. Server and Client have to authenticate each other with the mentioned Certificates.
So the whole data Transfer is encrypted and the Devices (Desktop and MID) can be sure they talk with the right Machine.
Android Desktop Integration
1I’m more or less finished with an initial Version of the Android App and Desktop Software. The Desktop part consists of 2 Elements. First is the Server running in the Background (no Gui) and Second is an Applet.
The Server shows Desktop Notifications and sends Information to the Applet via Dbus. The Applet is specific to the Desktop Environment (Gnome, Unity,…) you use. The Gnome Shell Version is ready and a Demo can be seen in this Video
I didn’t show the File Transfer and some other stuff, but this is how it will look like.
I’m currently fixing some Bugs, after that I’ll release a first version for Gnome and start working on a Unity Applet. I’ll also describe how the whole Security works in another Post.
Upcoming Project
0I’ve been busy with a new Project lately. It’s an Android App in combination with a Desktop Application, to integrate a Smart-phone in the normal Desktop UI.
I’ve seen “Android Notifier” and “KDE Connect”, both are awesome but don’t work well with Gnome Shell or Ubuntu Unity. There are many Apps out there which already notify you on your Desktop Computer, but most of them are Browser-Extensions which need a Third-party Server (your data is routed over some other website).
So the plan is a new Android App which communicates over the LAN with a Software running on Linux, Windows or Mac. I’m almost finished with the Linux Gnome Shell version and want to release it on Github soon.

Just released our Smart Howl App for Android. It is designed for mute People or People having problems with speaking. The Application let’s you talk with someone via Text-to-Speech. You can say already stored Texts or build new Sentences by simply drag and drop the Text you need.
Here’s an example Video of how you can use it:
New Features are already planned and are coming soon.
The Demo and Full Version will be up on Google Play soon.
