The universally composable symbolic analysis (UCSA) framework layers Dolev-Yao style symbolic analysis on top of the universally composable (UC) secure framework to construct computationally sound proofs of cryptographic protocol security. The original proposal of the UCSA framework by Canetti and Herzog (2004) focused on protocols that only use public key encryption to achieve 2-party mutual authentication or key exchange. This thesis expands the framework to include protocols that use digital signatures as well. In the process of expanding the framework, we identify a flaw in the framework's use of UC ideal functionality FKE. We also identify issues that arise when combining FKE with the current formulation of ideal signature functionality FSI,. Motivated by these discoveries, we redefine the FPKE and FsIG functionalities appropriately.
