This cannot be answered in an off-hand fashion or as an addon feature, but security and usability need to be taken into account right from the start. Seamless design cooperation of both is vital in achieving secure user experience. In this paper we discuss how security and user design guidelines within the ubiquitous future environment can be used to enhance both the security and user experience of the communication services. The paper brings forth network, service and user level aspects that need to be kept in mind when considering the technology oriented design processes of such networks.
