Abstract— In the Internet of Things (IoT) era, the importance
of communication technology to support communication
between the various types of devices has become greater
than ever before. Long Range (LoRa) and Long Range Wide
Area Network (LoRaWAN) are newly designed communication
technologies for low-power long-distance communication
in the IoT environment. Recently, LoRa and LoRaWAN have
received much attention in academia and industry because lowpower
long-distance communication has not been supported
by traditional communication technologies. Current LoRaWAN
supports only communication between the end node and the
central server. A recently introduced study enables device-todevice
(D2D) communication in the LoRaWAN environment,
which is not supported by the current LoRaWAN standard.
This paper shows that direct communication between devices
can reduce battery consumption. However, security is not considered
in this paper and the security features of the LoRaWAN
standard are also not applicable, which means that LoRaWAN
D2D communication is exposed to a security threat. Therefore,
we propose a secure link establishment scheme to protect the
LoRaWAN D2D communication. With our scheme, both D2D
nodes can securely share cryptographic keys for protecting the
D2D communication. Through the security analysis, we prove
that our scheme guarantees mutual authentication, confidentiality,
and integrity. Performance evaluation shows that our scheme
increases power consumption by approximately 5% compared
with the basic scheme without security, but has little impact
on overall battery lifetime. Consequently, the proposed scheme
guarantees fundamental security requirements with sufficient
