Abstract
The evolution of Internet of Things (IoT) is changing
traditional perceptions of the current Internet towards a
vision of smart objects interacting with each other. Wireless
Sensor Networks play an important role and support different
applications domains in the IoT environment. However, security
issues are the major obstacle for their deployment. Among these
issues, authentication of the different interconnected entities.
In this paper, we are interested to the case of the interconnection
of a sensor node with a remote user. We propose a
new lightweight authentication scheme adapted to the resource
constrained environment. This scheme allows both of the sensor
and the remote user to authenticate each other in order to
secure the communication. Our scheme uses nonces, exclusiveor
operations, and Keyed-Hash message authentication to check
the integrity of the different exchanges. Moreover, it provides
authentication with less energy consumption, and it terminates
with a session key agreement between the sensor node and the
remote user. To assess our scheme, we carry out a performance
and security analysis. The obtained results show that our scheme
saves energy, and provides a resistance against different types of
attacks.
