Hi All,
I have a question about the hop-by-hop authentication in BSP..

On each hop, the receiving node validates the integrity of bundle and
performs authentication of forwarder (source or intermediate forwarder)...
What benefits we get from this process ? What level of trust we have to
assume ? ... This security feature can only provide integrity of data and
nothing more than that ?
If a malicious node can sign the bundle and forward it, then the forwarder
can verify the integrity but, still it will forward...

In short, What are the assumptions on which BSP works ? ..

many thanks..

kind regards,
Shoaib
