Cryptographic group actions and applications
WebIn this paper we propose efficient two-party protocols for obliviously applying a (possibly random) linear group action to a data set. Our protocols capture various applications such as oblivious shuffles, circular shifts, matrix multiplications, to name just a few. WebAbout. Two years of floor mat design for vehicles.

WebOur framework generalizes the works of Brassard and Yung (Crypto’90) and Couveignes (Eprint’06). We provide new definitions for group actions endowed with natural hardness … WebIsogeny-based assumptions often have unique efficiency and security properties, which makes building new cryptographic applications from them a potentially tedious and time-consuming task. In this work, we propose a new framework based on group actions that enables the easy usage of a variety of isogeny-based assumptions.
WebApr 16, 2024 · We give the first black box lower bound for signature protocols that can be described as group actions, which include many based on isogenies. We show that, for a large class of signature schemes making black box … WebWe introduce a new assumption over group actions called Linear Hidden Shift (LHS) assumption. We then present some discussions on the security of the LHS assumption …

This lack of structure allows them to be plausibly quantum resistant despite Shor’s algorithm, while still having a number of applications. The most famous example of group actions are built from isogenies on elliptic curves.
