We study the secure transmissions for channel-aware (CA) random access based on the notion of physical layer security in this paper, which might be suitable for machine type communications. Thanks to the availability of channel state information in CA random access, opportunistic jamming can be employed to improve the secrecy rate. As a result, a positive secrecy rate can be obtained even if the signal-to-noise ratio at an eavesdropper is higher than that at a legitimate receiver. Since a… CONTINUE READING
