Titel: Secure Key Exchange and Encryption Mechanism for Group Communication in Wireless Ad Hoc Networks
Auteur: S. Sumathy

Verschenen in: The international journal on applications of graph theory in wireless ad hoc networks and sensor networks : J GRAPH-HOC
Paginering: Jaargang 2 (2010) nr. 1 pagina's 9-16
Jaar: 2010
Inhoud: Secured communication in ad hoc wireless networks is primarily important, because the communicationsignals are openly available as they propagate through air and are more susceptible to attacks rangingfrom passive eavesdropping to active interfering. The lack of any central coordination and sharedwireless medium makes them more vulnerable to attacks than wired networks. Nodes act both as hostsand routers and are interconnected by Multi- hop communication path for forwarding and receivingpackets to/from other nodes. The objective of this paper is to propose a key exchange and encryptionmechanism that aims to use the MAC address as an additional parameter as the message specific key[toencrypt]and forward data among the nodes. The nodes are organized in spanning tree fashion, as theyavoid forming cycles and exchange of key occurs only with authenticated neighbors in ad hoc networks,where nodes join or leave the network dynamically.
