Pass observed that universal composable zero-knowledge (UCZK) protocols in the common reference string (CRS) model, where a common reference string is selected trustily by a truste...
Abstract. Algorithmic progress and future technology threaten today’s cryptographic protocols. Long-term secure protocols should not even in future reveal more information to aâ€...
We build concurrently executable blind signatures schemes in the common reference string model, based on general complexity assumptions, and with optimal round complexity. Namely, ...
Abstract. Cryptographic protocols are often designed and analyzed under some trusted set-up assumptions, namely in settings where the participants have access to global information...

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