I'm working on a small application to distribute flooding traffic in a mobile 
adhoc network. The application use retransmission and duplicate suppression at 
the moment, but it has no way to authentificate the broadcasted messages.

The easiest sollution seems to sign a hash value of every package with a 
asymmetric public key and check this signature at the receiver/retransmitter.

Can I use the gnutls api for this case ? Each node will have a X509 keyring 
with the public keys of all nodes and signed by a trusted root CA, so key 
distribution is not necessary.
