useful. What is the scenario in which (presumably unlike some other keyed
MAC algorithms) RMAC is resistant to birthday attacks? More broadly for an
arbitrary keyed MAC (in a plausible application!) how does the birthday

I think they are presuming there will be no encryption, so Eve can
verify collisions by observing the MAC values. Eve just records
messages and their MACs that Alice sends Bob. They are also presuming
exceedingly long lived MAC keys. (If you changed keys the collection
of messages would have to
I've been trying to figure out whether the following attack will be
feasible in a Pd system, and what would have to be incorporated to prevent
against it.
Alice runs trusted application T on her computer. This is some sort of
media application, which acts on encoded data streamed over the
