Abstract:

     Wireless communications are vulnerable to eavesdropping attacks due to their broadcast nature. To deal with their emerging challenge of physical layer security, this talk studies the eavesdropping attacks in wireless networks. The goal is to obtain the optimal power allocation strategy in order to achieve the maximum secrecy capacity. However, realizing this goal is not trivial because we need to address two challenging research questions: (1) the channel capacity of main channel is poor; and (2) the jammer is not always friendly. To tackle the two challenges mentioned above, we employ the game theory to provide a flexible method that studies how the jammers, relays and source interact and cooperate with each other for resource allocation and profit acquisition.
