[Help-gnutls] Signing multicast traffic with gnutls API ?

[Henning Rogge]

Hello,

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.
