DeskCon Connection Security2
First 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.
