The wireless caching has attracted a lot of attention in recent years, since it can reduce the backhaul cost significantly and improve the user-perceived experience.
The existing works on the wireless caching and transmission mainly focus on the communication scenarios without eavesdroppers.
When the eavesdroppers appear, it is of vital importance to investigate the physical-layer security for the wireless caching aided networks.
In this paper, a caching network is studied in the presence of multiple eavesdroppers, which can overhear the secure information transmission.
We model the locations of eavesdroppers by a homogeneous Poisson Point Process (PPP), and the eavesdroppers jointly receive and decode contents through the maximum ratio combining (MRC) reception which yields the worst case of wiretap.
Moreover, the main performance metric is measured by the average probability of successful transmission, which is the probability of finding and successfully transmitting all the requested files within a radius R .
We study the system secure transmission performance by deriving a single integral result, which is significantly affected by the probability of caching each file.
Therefore, we extend to build the optimization problem of the probability of caching each file, in order to optimize the system secure transmission performance.
This optimization problem is nonconvex, and we turn to use the genetic algorithm (GA) to solve the problem.
Finally, simulation and numerical results are provided to validate the proposed studies.
