Dalam surat ini, kami menyiasat keselamatan lapisan fizikal dalam rangkaian berbilang geganti berbilang pengguna, di mana setiap geganti bukan sekadar pembantu tradisional, tetapi pada masa yang sama, boleh menjadi penyadap yang berpotensi. Kami mula-mula mencadangkan skim pemilihan pengguna kerumitan rendah dan geganti yang cekap untuk mengurangkan dengan ketara jumlah anggaran saluran serta jumlah pautan berpotensi untuk perbandingan. Untuk skim yang dicadangkan, kami memperoleh ungkapan bentuk tertutup untuk batas bawah kadar kerahsiaan ergodik (ESR) untuk menilai prestasi kerahsiaan sistem. Hasil simulasi disediakan untuk mengesahkan kesahihan ungkapan kami dan menunjukkan cara skala ESR dengan bilangan pengguna dan geganti.

Abstract: In this letter, we investigate the physical layer security in multi-user multi-relay networks, where each relay is not merely a traditional helper, but at the same time, can become a potential eavesdropper. We first propose an efficient low-complexity user and relay selection scheme to significantly reduce the amount of channel estimation as well as the amount of potential links for comparison. For the proposed scheme, we derive the closed-form expression for the lower bound of ergodic secrecy rate (ESR) to evaluate the system secrecy performance. Simulation results are provided to verify the validity of our expressions and demonstrate how the ESR scales with the number of users and relays.
