Abstract: | Previous research on security of network coding focused on the protection of data dissemination procedures and the detection of malicious activities such as pollution attacks.The capabilities of network coding to detect other attacks have not been fully explored.In this paper,we propose a new mechanism based on physical layer network coding to detect wormhole attacks.When two signal sequences collide at the receiver,the starting point of the collision is determined by the distances between the receiver and ... |
