الملخص EN

This paper investigates the secure communications of multiuser untrusted amplify-and-forward relay networks in the presence of direct links.

In the considered system, one user is selected among multiple ones for secure transmission to the destination node with the help of an untrusted relay node.

To reduce the information leakage to the untrusted relay, the paper considers two selection criteria to select the user based on the direct and the relaying links, respectively.

The impact of direct and the relaying link on the system secrecy performance is studied by deriving the close-form ergodic secrecy rate (ESR) as well as the asymptotic expression.

From the asymptotic expression, it can be found that the asymptotic ESR increases linearly with the logarithm of the average channel gain ratio of the direct link to the relaying link.
