Information Detection and Energy Harvesting Trade-off in Multi-User Secure Communication |

|---|---|---|
We study the secrecy rate region of wiretap interference channels with a multi-antenna passive eavesdropper under receiver energy harvesting constraints. To stay operational in the network, the legitimate receivers demand energy alongside information, which is fulfilled by power transmission and exploiting a power splitting (PS) receiver. Simultaneous wireless information and power transfer (SWIPT) results in a reduction in the secrecy rates due to the legitimate receivers PS for simultaneous information detection and energy harvesting. For this setup, lower-bounds for secure communication rate are derived without imposing any limitation on the eavesdropper processing. It turns out that in order to obtain the Pareto boundary of the secrecy rate region, smart tuning of the transmit power and receiver PS coefficient is required. Notice that, granting both, i.e., secrecy in communication as well as enabling energy harvesting, result in shrinkages in the reliable communication rate region, which is captured by this optimal tune. Hence, it is of crucial importance to investigate, which of these two services shrinks the rate region more. Interestingly, we observe that by enabling SWIPT, the convexity of the reliable rate region is preserved. However, granting secrecy for the communication results in a non-convex rate region as the interference power increases. |
