Hi Wassim, 

Thanks your point. 

In principle, I doubt that SeND (and even OptiSeND)
can be applied for 6lowpan environment, we need 
further study in the next version though. 6lowpan
node is more power/resourse sensitive than you are
referring to OptiSeND nodes in your proposal. 

I don't have a clear answer on that at this stage, so
we am focusing on *analysis* first, not *solution*.

Anyway, I will refer to your effort, and appreciate
if you have more comments on NDP security analysis
in conjunction with 6lowpan.

Regards.

=> I agree with you that SEND is unusable (too heavy for even
"normal" small mobile devices) but am not sure about your comment
on OptiSEND. In fact, the One-way hash chains and symmetric keys
(which are the main features in OptiSEND) are considered cheap
enough to be used to authenticate messages in these environments.

=> OK thanks.
