  In this paper, we investigate the physical layer security capabilities of
reconfigurable intelligent surface (RIS) empowered wireless systems. In more
detail, we consider a general system model, in which the links between the
transmitter (TX) and the RIS as well as the links between the RIS and the
legitimate receiver are modeled as mixture Gamma (MG) random variables (RVs).
Moreover, the link between the TX and eavesdropper is also modeled as a MG RV.
Building upon this system model, we derive the probability of zero-secrecy
capacity as well as the probability of information leakage. Finally, we extract
the average secrecy rate for both cases of TX having full and partial channel
state information knowledge.
