Original Abstract Submitted

Enhanced mechanism for detecting fake base station attacks In cellular or other wireless networks, false or fake base stations (FBS) behave as proper base stations managed by the network operator and aim at attracting wireless communication devices with different goals including FBS or man-in-the-middle (MitM) attacks. To detect and/or avoid such FBS or MitM attacks, it is proposed to securely perform a random-access procedure between a User Equipment, UE, and an access device in a wireless network, wherein the method comprises: receiving an L-bit sequence s received from the UE; extracting a k-bit value V by masking s with a mask; and sending V.
