Routing
nCorrect message
qB®E: I have a path to
G as <B, A, G>
nMalicious message
qD masquerades as B to E and says
B®E: I have a better path to G as <C, F, G>
qIf D is believed
E will never be able to
send messages to G.
qProposed solution – Have routing information digitally signed by B’s private key
