[en] This work investigates the security and reliabil-
ity analysis for a novel satellite-terrestrial (SatTer) network.
Specifically, a satellite attempts to transmit confidential infor-
mation to a ground user (GU) via the support of multiple
relay nodes in the presence of an eavesdropper that tries to
overhear the information. A friendly jammer is deployed to
improve the secure transmission between the satellite and the
relays. Furthermore, satellite-to-relay generalized Rician fading
channels and imperfect channel state information (CSI) are
deployed to examine a general system model. In this context,
the closed-formed expressions for the outage probability (OP)
and intercept probability (IP) are derived corresponding to
an amplify-and-forward (AF)-based relaying scheme, which is
challenging and has not been studied before. Finally, the exactness
of the mathematical analyses is validated through Monte Carlo
simulations. Furthermore, the effects of various key parameters
(e.g., channel estimation errors, satellite’s transmit power, relay’s
transmit power, number of relays, and fading severity parameter)
are examined
