Abstract	This paper proposes a novel amplify-and-forward with cooperative-jamming (ACJ) scheme. In order to make a balance between secrecy capacity (SC) and energy consumption, we use $R_{Sε}$ which is defined as the maximum equivalent SC for each unit of energy consumption to evaluate the performance of wireless communications. This paper shows that although SC increases with energy consumption, $R_{Sε}$ is not a monotone increasing function. That is to say, when energy consumption exceeds a specific value, the efficiency of each unit of the energy consumed decreases in aspects of the security. In this paper, we not only study the variation tendency of SC changing along with energy consumption, but also use the eigenvalue method to derive a precise equation of $R_{Sε}.$ Moreover, simulation results also demonstrate that our model performs quite well in terms of lowering energy consumption to the least, while guaranteeing the security requirements in wireless cooperative networks.
