Universally Composable Symbolic Analysis of Cryptographic Protocols (The case of encryption-based mutual authentication and key exchange).
Ran Canetti, Jonathan C. Herzog · 2004
Symbolic analysis of cryptographic protocols is dramatically simpler than full-fledged cryptographic analysis. In particular, it is readily amenable to automation. However, symbolic analysis does not a priori carry any cryptographic soundness guarantees. Following recent work on cryptographically sound symbolic analysis, we demonstrate how Dolev-Yao style symbolic analysis can be used to assert the security of cryptographic protocols within the universally composable (UC) security framework. Consequently, our methods enable security analysis that is completely symbolic, and at the same time cryptographically sound with strong composability properties.
