Building Secure Cryptographic Transforms, or How to Encrypt and MAC

Tadayoshi Kohno, Adriana Palacio, and 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.
