| Resumo: |
In this work, an improvement in the recently proposed performance metric effective secrecy throughput (EST) is presented, which, more than taking into account the secrecy rate and the secrecy outage probability, also limits the outage probability of the eavesdropper (Eve). Thus, the proposed scheme limits the maximum amount of information that Eve might be able to obtain of all the information sent by Alice. Under this new metric, referred to as EST with eavesdropper outage constraints, the impact on the system performance when considering a multiple-input multiple-output multiple-antenna eavesdropper (MIMOME) radio frequency and free-space optical (FSO) scenarios are evaluated. For the FSO scenario, it is also shown how the use of relays can increase the EST. Numerical results are performed to validate the analytical expressions, demonstrating the influence of limiting the maximum amount of information that might be obtained by Eve. |
