A Universally Composable Cryptographic Library
Michael Backes, Birgit Pfitzmann, Michael Waidner · 2003
Bridging the gap between formal methods and cryptography has recently received a lot of interest, i.e., investigating to what extent proofs of cryprographic protocols made with abstracted cryptographic operations are valid for real implementations. However, a major goal has not been achieved yet: a soundness proof for an abstract crypro-library as needed for the cryptographic protocols typically proved with formal methods, e.g., authentication and key exchange protocols. Prior work that directly justifies the typical Dolev-Yao abstraction is restricted to passive adversaries and certain protocol environments.
