A Lightweight Group Authentication scheme over Lattices

Authentication has advanced in various fields; however, numerous authentication systems are induced via conventional cryptographic natives. Such natives don’t make it broadly acknowledged and impenetrable to quantum calculations. Under any circumstances, these schemes assist in the instance of a single user. Following the recently suggested glitches, we propose a lattice-based group authentication scheme. The proposed scheme is protected from replay attacks and man-in-the-middle attacks. Similarly, differentiated and existing lattice-based authentication schemes provide the most useful strategy for agreeing on session keys among a huddle of users, followed by our shared authentication.
