Lightweight Swarm Authentication

George Teseleanu

Abstract

In this paper we describe a provably secure authentication protocol for resource limited devices. The proposed algorithm performs whole-network authentication using very few rounds and in a time logarithmic in the number of nodes. Compared to one-to-one node authentication and previous proposals, our protocol is more efficient: it requires less communication and computation and, in turn, lower energy consumption.
