Cryptographic reductions
One of the main tools of cryptography are reductions. The simplest way to prove the security of a complex scheme based on the security of its constituents is to prove that if there exists an adversary that breaks the complex scheme then we can construct an adversary that breaks at least one of the constituent primitives. Since the security of the primitive is taken as a premise, this gives a co...
متن کاملBounded Reductions
We study properties of resource{ and otherwise bounded reductions and corresponding completeness notions on nondeterministic time classes which contain exponential time. As it turns out, most of these reductions can be separated in the sense that their corresponding completeness notions are diierent. There is one notable exception. On nondeterministic exponential time, 1-truth table and many-on...
متن کاملLocal Reductions
We reduce non-deterministic time T ≥ 2n to a 3SAT instance φ of size |φ| = T · log T such that there is an explicit circuit C that on input an index i of log |φ| bits outputs the ith clause, and each output bit of C depends on O(1) inputs bits. The previous best result was C in NC1. Even in the simpler setting of |φ| = poly(T ) the previous best result was C in AC0. More generally, for any time...
متن کاملChemical Reductions Do Not Necessarily Lead to Computational Reductions
The comparison of solutions of the shock-ignition of a hydrogen bubble in air using detailed and reduced chemical mechanisms is presented. The reduced chemical kinetics mechanism with 9 species and 12 irreversible reactions is obtained using the G-Scheme. The test shows that the simulation becomes computationally more expensive using the reduced mechanism.
متن کاملPhytochemical composition of nuts.
Observational studies suggest nut consumption is inversely associated with the incidence of cardiovascular disease and cancer. In addition to being rich in several vitamins and minerals, unsaturated fatty acids, and fiber, tree nuts and peanuts contain numerous phytochemicals that may contribute to promoting health and reducing the risk of chronic disease. While many of these bioactive constitu...
