Abstract
Internet of Things (IoT) networks are becoming a part of our daily lives and
the number of IoT devices around us are surging. The authentication of millions
of connected things and the distribution and management of shared keys between
these devices pose challenging research problems. Current one-to-one
authentication schemes do not take the resource limitations of IoT devices into
consideration. Nor do they address the scalability problem of massive machine
type communication (mMTC) networks. Group authentication schemes (GAS), on the
other hand, have emerged as novel approaches for many-to-many authentication
problems. They can be used to simultaneously authenticate many
resource-constrained devices. However, existing group authentication schemes
are not energy efficient, and they do not provide enough security for
widespread use. In this paper, we propose a lightweight GAS that significantly
reduces energy consumption on devices, providing almost 80% energy savings
compared to the state-of-the-art solutions. Our approach is resistant to the
common replay and man-in-the-middle attacks.. The proposed approach also
includes a solution for key agreement and distribution in mMTC environments.
Moreover, this approach can be used in both centralized and decentralized group
authentication scenarios.
