| contents | Securing information in future mobile networks is challenging, especially for devices with limited computational resources. Physical layer security (PLS) offers a viable solution by leveraging wireless channel randomness. When full secrecy is unattainable, the partial secrecy regime provides a realistic alternative. This work analyzes partial secrecy performance under the generalized multicluster fluctuating two-ray (MFTR) fading model, which subsumes many classical fading cases. We study a system with a transmitter (A), legitimate receiver (B), and eavesdropper (E), both B and E using antenna arrays with maximal ratio combining (MRC), under i.n.i.d. fading. Exact and closed-form approximations are derived for key secrecy metrics: generalized secrecy outage probability (GSOP), average fractional equivocation (AFE), and average information leakage rate (AILR). The results, validated by Monte Carlo simulations, retain constant complexity regardless of diversity order. The MFTR model's flexibility enables comprehensive assessment across fading conditions, showing that more MRC branches at B enhance secrecy performance depending on the A-E link characteristics. |
