LESS-FM: Fine-Tuning Signatures from the Code Equivalence Problem

نویسندگان

چکیده

Code-based cryptographic schemes are highly regarded among the quantum-safe alternatives to current standards. Yet, designing code-based signatures using traditional methods has always been a challenging task, and proposals still far from target set by other post-quantum primitives (e.g. lattice-based). In this paper, we revisit recent work an innovative approach for signing, based on hardness of code equivalence problem. We introduce some optimizations provide security analysis all variants considered. then show that new parameters produce instances practical interest.

Automated FM-AFM Feedback Tuning

FM-AFM is an extremely powerful and versatile imaging technique capable of atomic resolution imaging in vacuum, air or liquid. However, obtaining such results in practice currently requires tedious and time consuming manual tuning of many feedback parameters by trial and error. We present a recently developed algorithm for automated tuning of FM-AFM feedback parameters. The algorithm optimizes ...

God, Fine-Tuning, and the Problem of Old Evidence

The fundamental constants that are involved in the laws of physics which describe our universe are finely tuned for life, in the sense that if some of the constants had slightly different values life could not exist. Some people hold that this provides evidence for the existence of God. I will present a probabilistic version of this fine-tuning argument which is stronger than all other versions...

The Fine-tuning Problem in Little Higgs Models

Little Higgs models represent an alternative to Supersymmetry as a solution to the Hierarchy Problem. After introducing the main physical ideas of these models, we present the fine-tuning associated to the electroweak breaking in Little Higgs scenarios. Taking into account the most general properties of this scenarios and focusing on two representative “Little Higgs” models, we find that the fi...

Problems With the Argument From Fine Tuning

The argument from fine tuning is supposed to establish the existence of God from the fact that the evolution of carbon-based life requires the laws of physics and the boundary conditions of the universe to be more or less as they are. We demonstrate that this argument fails. In particular, we focus on problems associated with the role probabilities play in the argument. We show that, even grant...
