Abstract

In a powerful secrecy attack, eavesdroppers can collude, i.e., they can share their observations. Securing information in such a scenario will be an even more challenging task compared to non-colluding case. We here analyze the effect of eavesdropper collusion on the achievable performance in both the path loss and er-godic multi-path fading models. We provide two results: 1) For the Poisson point process model in a random extended network, if the legitimate nodes have unit intensity (λ = 1) and the colluding eavesdroppers have an intensity of λe = O ((log n)-(2+p)) for any p > 0, almost all of the nodes can achieve a secure rate of Ω (1/√n); and 2) In the K-user Gaussian interference channel with E external colluding eavesdroppers, a secure degrees of freedom of η = [1/2 - E/K]+ per frequency-time slot is achievable for each user in the ergodic setting (in the absence of the eavesdropper channel state information).
