Vaudenay recently proposed a message authentication protocol which is interactive and based on short authenticated strings (SAS). We study here SASbased non-interactive message aut...
We construct efficient universally composable oblivious transfer protocols in the multi-party setting for honest majorities. Unlike previous proposals our protocols are designed in...

We construct a fully collusion resistant tracing traitors system with sublinear size ciphertexts and constant size private keys. More precisely, let N be the total number of users...
