Patent ID: 8433894

Claim:
A wireless transmit/receive unit (WTRU) device comprising: a processor; a computer-readable storage medium comprising computer executable instructions which, when executed by the processor, implement at least one of a physical layer, a medium access control (MAC) layer, and a security manager; the physical layer configured to receive a burst, perform measurements continuously, and report the measurements to the MAC layer to enable physical layer security; the MAC layer configured to process the measurements received from the physical layer, detect a potential attack based on the measurements, and send a security alert to the security manager upon detection of the potential attack; and the security manager configured to implement a counter-measure to the potential attack upon receipt of the security alert from the MAC layer to establish the physical layer security, wherein the measurement includes a channel impulse response (CIR), and the WTRU device further comprising: a database configured to associate a source MAC address of a received packet and the CIR measured on the burst carrying the packet, wherein the MAC layer is configured to check consistency of the source MAC address-CIR pair and detect the potential attack on a condition that the source MAC address-CIR pair is not consistent.
