Description
This detailed document presents an effective technique for reliable and secure communication
for IoT devices. Channel-dependent precoders
with dual-transmission approach are jointly exploited
to ensure a reliable as well as secure communication against
internal and external eavesdropping. More specifically, users’
pre-coded data is superimposed in the first step. Afterward, the
mixture is sent in two transmissions in such a way that after
combining signals from the first and the second transmissions,
the legitimate receivers will get the reliable signal without
complex processing while the external eavesdropper will get
the degraded version of the signal. Moreover, the proposed
algorithm also ensures that the users are also not able to
eavesdropper each other’s data. Simulation results proved that
the proposed algorithm can ensure secure communication and
suitable for IoT-based devices because it does not require
complex processing at the receivers. For future work, the
extension of the proposed algorithm for active eavesdropper
case will be considered.
