Title
Artificial Interference Aided Physical Layer Security in Cache-Enabled Heterogeneous Networks
Abstract
Caching popular contents is a promising way to offload the mobile data traffic in wireless networks, but so far the potential advantage of caching in improving physical layer security (PLS) is rarely considered. In this paper, we contribute to the design and theoretical understanding of exploiting the caching ability of users to improve the transmission security in a wireless heterogeneous network (HetNet). In such network, the base station (BS) ensures the secrecy of communication by transmitting the requested file along with a pre-cached file of the user, such that only the eavesdropper's channel is degraded. Accordingly, the node locations of BSs, users and eavesdroppers are first modeled as mutually independent poisson point processes (PPPs) and the corresponding file access protocol is developed. We then derive analytical expressions of two metrics, average secrecy rate and secrecy coverage probability, for the proposed system. Numerical results are provided to show the significant security advantages of the proposed scheme and to characterize the impacts of network resources on the security performance.
