Hi Julian,

I definitely think you have a point here. We can consider different security contexts for different tunnels, according to some policy agreed by both end-points at a given tunnel.
The security contexts would define encryption, authentication, or both. We'd have to go into more detail to evaluate potential savings, but I have the feeling they could be worth considering.

The point is that if we go for these different security contexts, we must consider how they can be established by mutual authentication of the tunnel end-points, and this opens additional issues regarding configuration and crypto material exchange, as well as the possibility of user-initiated authentication by means of protocols like OAuth.

I'd keep this in the list of the "soon-to-open" issues, focusing on the three main docs we have been discussing so far.

Be goode,

Hi all,
I like to add a potencial new idea which could be addressed by re-chartering. What about the security on the tunnel?. It is possible to add security to TCMTF because it is inherent in the tunnels. And not only consider encryption, but also the digital signature which represents much loss of efficiency in the case of small packages.
Someone have more knowledge about this issue?
Julián
