Secure Resource Allocation for Cooperative OFDMA System With Untrusted AF Relaying
In this paper, we consider a cooperative orthogonal frequency division multiple access (OFDMA) system, where a source communicates with multiple users with the help of an untrusted relay. Since we assume no direct links between source and users because of the shadowing effect, the positive secrecy r...
