This letter investigates the potentials of strengthening the network-wide physical layer security performance of the random access based wireless mutual broadcast (RA-WMB), where both transmitters and receivers are unspecified, under a stochastic geometry framework. Further, this study proposes the design principles of the key operation parameters including the transmission probability and friendly jammer density in terms of improving the spatial secrecy performance. The analysis and numerical results clarify the difference between the secure and nonsecure operations in the RA-WMB networks.
