Secret key generation (SKG) schemes have been shown to be vulnerable to denial of service (DoS) attacks in the form of jamming and to man in the middle attacks implemented as injection attacks. In this paper, a comprehensive study on the impact of correlated and uncorrelated jamming and injection attacks in wireless SKG systems is presented. First, two optimal signalling schemes for the legitimate users are proposed and the impact of injection attacks as well as countermeasures are investigated. Finally, it is demonstrated that the jammer should inject either correlated jamming when imperfect channel state information (CSI) regarding the main channel is at their disposal, or, uncorrelated jamming when the main channel CSI is completely unknown.
