Universally Composable Oblivious Transfer in the Multi-party Setting
We construct efficient universally composable oblivious transfer protocols in the multi-party setting for honest majorities. Unlike previous proposals our protocols are designed in...

Using ProVerif to Analyze Protocols with Diffie-Hellman Exponentiation
ProVerif is one of the most successful tools for cryptographic protocol analysis. However, dealing with algebraic properties of operators such as the exclusive OR (XOR) and Diffie-...

Universally Composable Password-Based Key Exchange
Abstract. We propose and realize a definition of security for passwordbased key exchange within the framework of universally composable (UC) security, thus providing security guar...
