A Provable-Security Treatment of the Key-Wrap Problem
Abstract. We give a provable-security treatment for the key-wrap problem, providing definitions, constructions, and proofs. We suggest that key-wrap's goal is security in the ...

Fully Simulatable Quantum-Secure Coin-Flipping and Applications
We propose a coin-flip protocol which yields a string of strong, random coins and is fully simulatable against poly-sized quantum adversaries on both sides. It can be implemented ...

On the (Im)Possibility of Key Dependent Encryption
We study the possibility of constructing encryption schemes secure under messages that are chosen depending on the key k of the encryption scheme itself. We give the following sep...
