Fixed AODV routing protocol
4.0
Application background A secure version of AODV called Secure AODV (SAODV).
It provides features such as integrity, authentication, and
non-repudiation of routing data. It incorporates two schemes
for securing AODV. To preserve the collaboration
mechanism of AODV, SAODV includes a kind of
delegation feature that allows intermediate nodes to reply to
RREQ messages. This is called the double signature : when
a node A generates a RREQ message, in addition to the regular signature, it can include a second signature, which is
computed on a fictitious RREP message towards A itself.
Intermediate nodes can store this second signature in their
routing table, along with other routing information related to
node A. If one of these nodes then receives a RREQ towards
node A, it can reply on behalf of A with a RREP message,
similarly to what happens with regular AODV. To do so, t
