We subsume these schemes under a more general class of blind signature schemes and show that finding security proofs for these schemes via black-box reductions in the standard model is hard. Technically, our result deploys meta-reduction techniques showing that black

Evaluation of Ventricular Repolarization of quantum physics. A scheme of that type relies on the quantum-physical phenomenon of . and on the assumption that no illegitimate information flows within and between Alice’s and Bob’s laboratories. The latter can be enforced via the non-signaling postulate of relativity if all measurements are c

Thorsten Lewalter MD,Berndt Lüderitz MDtacks are not an option. For such knapsacks, the current state-of-the-art is a 31-year old algorithm by Schroeppel and Shamir which is based on birthday paradox techniques and yields a running time of . for knapsacks of . elements and uses . storage. We propose here two new algorithms which improve

Here we revisit these fundamental algorithms and show that surprising exponential speedups can be achieved both in theory and in practice by using a new tec
