Providing Security Services in a Resource Discovery System

Nowadays, portable electronic devices allow users to access available resources wherever they are. In this sense, announcement and discovering of services and resources are two central problems to be solved in ubiquitous computing. Despite the fact that many service and resource discovery protocols exist, they are limited to a concrete network technology and most of them do not face mobility and security requirements for a global and ubiquitous solution. In this paper the authors introduce a Multiprotocol Service Discovery solution for heterogeneous networks and describe their work for including security as a main goal of the proposal.
