Title:
Building Secure Cryptographic Transforms, or How to Encrypt and MAC

Authors: Tadayoshi Kohno, Adriana Palacio, John Black

Abstract:

We describe several notions of ``cryptographic transforms,‘’
symmetric schemes designed to meet a variety of privacy and
authenticity goals. We consider goals, such as replay-avoidance and
in-order packet delivery, that have not been fully addressed in
previous works in this area. We then provide an analysis of
possible ways to combine standard encryption and message
authentication schemes in order to provably meet these
goals. Our results further narrow the gap between
the provable-security results from the theoretical community and the
needs of developers who implement real systems.
