In the absense of path valdiation, a method of determining the real
origin of a prefix is also required, if the goal is to prevent
intentional hijacking as well as unintentional origination. Simply
looking at the right-most entry in the AS_PATH doesn't cut it, since
anybody can "set as-path prepend P".
This suggests to me that either we can't separate origin validation
from path validation (which sucks the former into the more difficult
problems associated with the latter), or we need a better measure of
"origin" (e.g. a PKI and an attribute which carries a signature).
