Universally Composable Commitments
d Abstract) Ran Canetti and Marc Fischlin Abstract. We propose a new security measure for commitment protocols, called Universally Composable (UC) Commitment. The measure guarantee...

A Characterization of Non-interactive Instance-Dependent Commitment-Schemes (NIC)
Abstract. We provide a new characterization of certain zero-knowledge protocols as non-interactive instance-dependent commitment-schemes (NIC). To obtain this result we consider th...

Efficient Non-malleable Commitment Schemes
We present efficient non-malleable commitment schemes based on standard assumptions such as RSA and Discrete-Log, and under the condition that the network provides publicly availab...

Leakage Tolerant Interactive Protocols
We put forth a framework for expressing security requirements from interactive protocols in the presence of arbitrary leakage. This allows capturing different levels of leakage to...
