Hi all
Further to the last hangout, during which we discussed RFC7182/7183
being applied to AODVv2 messages. It struck me that while we can apply
an Integrity Check Vector (ICV) to a AODVv2 message, the 5444 parser
will set about compressing, rearranging and generally optimising the
content. It therefore strikes me (following a similar discussion on DTN)
that the 5444 parser at the far end must losslessly (and in the reverse
order) undo all its optimisations for the ICV to correctly compute,
otherwise an error will occur and the far end router may choose to
reject the message, fearing corruption or a Man In The Middle attack.
I was thinking about writing to Chris D to ask about how OLSRv2 works
around this, when it struck me that Henning would probably know and
Lotte has him in the loop just now.
So Lotte, please would you ask Henning what his thoughts are on this please?
Thanks and Best Regards
John
