Security and authentification with D-Bus

[Yoann Sculo]

Hello everyone,

I'm working with D-Bus to let a bunch of application talk together. It 
works great !
However, I'm wondering how D-Bus could provide authentification for my 
applications. Basically, I'd like to be sure a spy-application isn't 
usurping another application's identity. This is quite important for me 
in my context.

Somebody has outlined the idea of using a key authentification 
http://blog.vrplumber.com/index.php?/archives/219-Need-to-understand-the-dbus-security-model-Kind-of-a-key-requirement-to-analyse-security-when-everything-uses-it....html
Therefore I have found explanations in D-Bus specification 
http://dbus.freedesktop.org/doc/dbus-specification.html#auth-protocol.

but I'm surprised not to find any documentation or code about it (except 
for dbus specification)

I'm currently using Glib binding. Feeling lucky, I'm trying to know more 
about it at the source, here.
Do you have any idea (I suppose) how to manage a good authentification 
with D-Bus ? Is there any existing example ? (some piece of code which 
could help me)

I may have missed some documentation. I'd be pleased you show me the way !

Thank you

Regards

Yoann
