Delayed-Key Message Authentication for Streams
We consider message authentication codes for streams where the key becomes known only at the end of the stream. This usually happens in key-exchange protocols like SSL and TLS wher...

Expected loss bounds for authentication in constrained channels
We derive bounds on the expected loss for authentication protocols in channels which are constrained due to noisy conditions and communication costs. This is motivated by a numbe...

On Generating the Initial Key in the Bounded-Storage Model
Abstract. In the bounded-storage model (BSM) for information-theoretically secure encryption and key-agreement one uses a random string R whose length t is greater than the assumed...
