“…As the secrecy capacity may be less than target secrecy redundancy rate, the secrecy outage probability (SOP) has been applied to present a more comprehensive performance evaluation. For instance, [9] discussed a security region with AN based on SOP, and [10] minimized SOP in a D2D-enabled cellular network by access control. When a certain SOP constraint is required, secrecy throughput has widely been considered, especially in optimization problems where the transmission rate or power is adjusted for improved security [11,12].…”

In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency. First, we analyzed some critical performance metrics, including connection outage probability (COP), secrecy outage probability (SOP) and effective secrecy throughput (EST). Then, to maximize the EST, three optimization problems of rate adaption were discussed: (i) optimizing the code rate with a given secrecy redundancy rate by a parameterized closed-form solution; (ii) optimizing the secrecy redundancy rate with a given code rate by a fixed-point method; (iii) optimizing both code rate and secrecy redundancy rate by an iterative optimization algorithm. We also considered COP and SOP constraints among the problems while corresponding solutions were deduced. Finally, numerical and simulated results verified our conclusions that the approximated SOP matches well with Monte–Carlo simulation for a strict reliable constraint, and that the optimized transmitting rate enhances EST efficiently with multiple eavesdroppers and retransmissions. Moreover, the influence of the number of eavesdroppers on secrecy performance was analyzed. Briefly, secrecy performance inevitably deteriorates with increasing number of eavesdroppers due to raised information leakage.

This paper extends our previous work on multiple‐input–multiple‐output multiantenna eavesdropper–based wiretap channels aimed at fundamentally proposing optimally secure frameworks. This extension is appropriately conducted providing 2 newly asymptotic bounds for the secrecy outage capacity. Such proposed schemes should be necessarily taken into consideration owing to channel uncertainty sets in relation to the eavesdropping fusion center. Our first resultant closed‐form solution, which is mathematically performed according to Hanson‐Wright inequality, is totally tight as well; something that can be technically assigned to other ergodicity‐driven equilibria. Specifically, our solution's outperformance is highlighted with regard to a significantly more adequate secrecy capacity in the low signal‐to‐noise‐ratio regime. Such outperformance is efficiently guaranteed due to assigning optimally convex paradigms regarding the concentration‐of‐measure‐based inequality aforementioned. Additionally, our framework has a markedly acceptable computational complexity compared with our previous work. The latter characteristic is straightforwardly highlighted in parallel with a considerably acceptable computational error as well. Finally, we optimally generalise our framework to dynamically fast fading processes in terms of the secondly closed‐form asymptotic bound. At the end of the discussion, simulation‐based analytical results principally authenticate our contribution's efficiency and tightness.
