Key management has always been an issue in ad hoc networks. These networks are infrastructure-less which gives the attackers an open chance to intrude and operate it on their will. A lot of work has been done in the area but the techniques were either less secured or require too many computations and were based on asymmetric or symmetric key management cryptographic schemes. The employment of such...
The research in mobile ad hoc networks has been gaining ground for its ease of random deployment. There might be more than a single MANET group around, operating independently. The mobility factor cannot restrict the nodes to a single location or a MANET group that aggravates the authentication issues. The authentication of nodes among different MANET groups is not trivial when considered in a broad...
Authentication is a key requirement in security of integrated wireless networks. A Mobile Node (MN) requires to be re-authenticated whenever it performs vertical handoff in integrated wireless networks. The re-authentication causes delay in communication. If MN is not re-authenticated, it causes an even more serious problem of unauthorized entry in a network. In order to solve this problem, we have...
