Error-free message transmission in the universal composability framework
… for error-free communication in the Universal Composability framework. Realizing these functionalities enables protocols to make use of cryptographic error-correcting schemes which are more powerful than classical codes. First, we define new ideal functionalities TrCLOSE and FCWT to …

On Black-Box Complexity and Adaptive, Universal Composability of Cryptographic Tasks
… for multiparty computation (MPC) in the Universal Composability (UC) model that are secure against malicious, adaptive adversaries. In the standard model, security is only guaranteed in a stand-alone setting; however, nothing is guaranteed when multiple protocols are arbitrarily composed. …

A calculus for composable, computational cryptography
The universal composability (UC) framework is the established standard for analyzing cryptographic protocols in a modular way, such that security is preserved under concurrent composition with arbitrary other protocols. However, although UC is widely used for on-paper proofs, prior attempts at …
