▪Wireless link signature may be a physical layer authentication mechanism, victimisation the multipath impact between a transmitter and a receiver to produce authentication of wireless signals. This paper identifies a brand new attack, known as mimicry attack,against the present wireless link signature schemes. associate degree assaulter can forge a legitimate transmitter’s link signature as long because it knows the legitimate signal at the receiver’s location, and the attacker doesn't have to be compelled to be at precisely the same location as the legitimate transmitter. we tend to conjointly extend the mimicry attack to multiple-input multiple-output (MIMO) systems, and conclude that the mimicry attack is possible only if the quantity of attacker’ antennas is up to or larger than that of the receiver’s antennas. To defend against the mimicry attack, this paper proposes a unique construction for wireless link signature, called time-synched link signature, by integration cryptographical protection and time issue into wireless physical layer options. Experimental results make sure that the mimicry attack may be a real threat and therefore the freshly planned time-synched link signatures area unit effective in physical layer authentication.
