Abstract
This paper provides a closed-form expression for Outage Secrecy Capacity in Wireless Information-Theoretic Security. This is accomplished on the basis of an approximation of the exponential function via a first-order Taylor series. The error of this method is calculated for two different channel cases, and the resulting precision confirms the correctness of this approach. Thus, the Outage Secrecy Capacity can be calculated for a given Outage Probability and for a given propagation environment (path loss exponent, average main channel SNR), allowing us to estimate with increased precision the boundaries of secure communications.
