Yes, I am aware of this. As with this approach signature messages only
travel one hop, to solve the problem we are planning to use session
keys and multiple symmetric signature messages based on that session
Another big issue is the fact that as each node has a subjective view
of the network, in terms of trust metric, routing loops may occur.
