Packet Authentication in Wireless Mesh Network

In Today's networking areas, Wireless Mesh Network (WMN) has become one of the most evolving research works due to its challenges in its security and its adaptable applications. Different kinds of attacks are possible in WMNs like DoS (Denial of Services), man-in-the-middle (MitM), replay, impersonation etc., which led to the vulnerability of security attacks in Wireless Mesh network. And many existing schemes were proposed to deliver node authentication, which does only deliver end-to-end authentication between the two communicating nodes with their secret key. Therefore, the intermediate nodes only forward the packet and only the destination node authenticates the packet. Which implies that the success chance of DoS attack and packet drop is very high and these results in the increase of network collision decrease the packet delivery ratio and high consumption of power. Therefore, we propose a hop-by-hop packets authentication with having data confidentiality, which is the most effective ways to obstruct attacks and stop forwarding of corrupted and unauthorized traffic in WMN. In this paper, we present a Packet Authentication with Data Confidentiality (PADC) rely on Elliptic Curves Cryptography in WMN. This enables authentication in the intermediate nodes while the confidentiality and integrity of data is preserved throughout its transmission until it reaches its destination.
