Domínios Virtuais para Redes Móveis Ad Hoc

Leonardo A. MartucciTereza C. M. B. CarvalhoWilson V. Ruggiero

This paper describes a security mechanism that assures privacy aspects on wireless ad hoc networks. Trusted devices initially compose these networks and information regarding to their composition or even their location, cannot be obtained from non-authorized parties. Security is achieved splitting the ad hoc network into groups of trusted devices, called virtual domains. Only devices that belong to a virtual domain can find or identify other devices from the same virtual domain. Furthermore, each virtual domain is defined by a sequence given by a time-correlated pseudo-random number generator. The security mechanism described in thispaper is not exclusive to ad hoc networks and could be applied on several other network environments.
