Post-Quantum Group-Oriented Authentication in IoT
E. B. Aleksandrova, A. A. Shtyrkina, and A. V. Yarmak

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.

Key words: post-quantum cryptography, group-oriented authentication, digital signature, latticebased cryptography, information security
