Wireless Mesh Networks (WMNs) capability for self-organization reduces the complexity of network deployment and maintenance, and thus, offers inexpensive wireless coverage over large areas via use of wireless multi-hopping to wire line gateway nodes. Securing WMNs is a great challenge of because they are subject to various kinds of attacks due to their dynamic wireless and distributed nature. Various security mechanisms based on cryptographic keys involving a high degree key management were used in WMNs. One such secure scheme SKeMS that implements an encryption key assignment and is very effective in reducing eavesdropping attacks, usual threat in WMNs. Compared with previous schemes, SKeMS assigns the available encryption keys among all the nodes in the network.
