Post-Quantum Group-Oriented Authentication in IoT

Abstract

The Internet of Things may include sensors, actuators, analyzers, logical controllers, which together form distributed network of heterogeneous devices. Group-based approach to authentication may be relevant when the number of nodes is very large and there are constrained devices among them. Post-quantum schemes as candidates in NIST competition are considered. Lattices are chosen as best candidates for building group-oriented schemes for IoT due to high performance, relatively small key sizes, well researched mathematical problem. To give flexibility to the lattice-based group-oriented authentication protocols, the basis delegation mechanism was considered as an approach that takes into account the hierarchy in the Internet of Things systems.
