Security Notions and Generic Constructions for Client Puzzles
Computational puzzles are mildly difficult computational problems that require resources (processor cycles, memory, or both) to solve. Puzzles have found a variety of uses in secu...

On Constructing Locally Computable Extractors and Cryptosystems in the Bounded Storage Model
We consider the problem of constructing randomness extractors that are locally computable; that is, read only a small number of bits from their input. As recently shown by Lu (thi...

Secure Computability of Functions in the IT Setting with Dishonest Majority and Applications to Long-Term Security
It is well known that general secure function evaluation (SFE) with information-theoretical (IT) security is infeasible in presence of a corrupted majority in the standard model. ...

Bounded-Concurrent Secure Two-Party Computation in a Constant Number of Rounds
We consider the problem of constructing a general protocol for secure two-party computation in a way that preserves security under concurrent composition. In our treatment, we foc...
