On May 15, 2019, Prof. Jiajia Liu from Xidian University gave a talk about "Cooperative Jamming in Wireless Networks with Eavesdroppers at Arbitrary Locations". This report mainly introduced cooperative jamming for physical layer security enhancement in the presence of multiple eavesdroppers, The basic idea was to transmit the message in multiple rounds such that each eavesdropper can only obtain partial information about the message, Stochastic geometry based analytic results as well as Monte Carlo simulations were presented to illustrate the achievable secrecy performances.
