• Information-theoretic security
• cooperative jamming
• relaying chatting
• outage probability

In this letter, we study the opportunistic use of relays for secret communications, and propose two transmission schemes that do not require the knowledge of the eavesdropper's channel state information. Both analytic and numerical results are provided.
