Secure Degrees of Freedom Regions of Multiple Access and Interference Channels: The Polytope Structure

Preprint English OPEN
Xie, Jianwei; Ulukus, Sennur;

The sum secure degrees of freedom (s.d.o.f.) of two fundamental multi-user network structures, the K-user Gaussian multiple access (MAC) wiretap channel and the K-user interference channel (IC) with secrecy constraints, have been determined recently as K(K-1)/(K(K-1)+1)... View more
