This paper studies the physical layer security (PLS) of underlay multihop device-to-device (D2D) relaying. New closed-form expressions on the lower bound of the outage probability, the secrecy outage probability (SOP), and the probability of non-zero secrecy capacity are derived. Hence, new insights into the secrecy performance of the underlay multihop D2D relaying are revealed. The obtained analysis is validated through Mont-Carlo simulations.
