Two-hop wireless network is the basic network model for the study of general wireless networks, while cooperative jamming is a promising scheme to achieve the physical layer security. This paper establishes a theoretical framework for the study of eavesdropper-tolerance capability (ETC, i.e., the exact maximum number of eavesdroppers that can be tolerated) in a two-hop wireless network, where the cooperative jamming is adopted to ensure security defined by secrecy outage probability (SOP) and opportunistic relaying is adopted to guarantee reliability defined by transmission outage probability (TOP). For the concerned network, closed form modeling for both SOP and TOP is first conducted, base on which the model for ETC analysis is then developed. Finally, numerical results are provided to illustrate the efficiency of our theoretical framework.
