Authentication, Authorization and Accouting in OLSR (AAA)

Thanks Henning for comments........
I have one more question.... Suppose a particular node is in network and
discovered the neighbors using OLSR TC and hello messages.
Now without using the crypto keys any node cannot get the message or
data correctly.. Am I right?
Then If we use X-supplicant (open source which use EAP massages over
Ethernet or radius) and/or Radius (open source) then the user can be
authenticated and registered before starting communication using TLS
certificates. We used this TLS (Transport Layer Security) mechanism in
mobile IP. Is it fesiable with OLSR?

There will be a 0.6.0 release of OLSR, but it will contain no AAA. This
is out of scope for the routing daemon I think.

The secure plugin does a authentification based on a shared group secret
for the routing messages.

It depends what kind of security do you need. Do you just have to keep
out attackers which do NOT get a copy of your crypto keys ? Then just
encrypt everything on link-layer with a common group key.
Do you want to have security even against attackers who are already
inside your network (for example who have stolen a device) ? Then you
need some additional stuff like authenticated routing messages (not the
secure plugin, because it's based on a shared GROUP secret), IPsec and
some other mechanisms.
