Deniable Authenticated Key Establishment for Internet Protocols

We propose two public-key schemes to achieve “deniable authentication” for the Internet Key Exchange (IKE). Our protocols can be implemented using different concrete mechanisms and we discuss different options; in particular we suggest solutions based on elliptic curve pairings. The protocol designs use the modular construction method of Canetti and Krawczyk which provides the basis for a proof of security. Our schemes can, in some situations, be more efficient than existing IKE protocols as well as having stronger deniability properties.

The relationship between Internet use and perceived performance in retail and professional service firms

lnformation technology (IT) and, in particular, the Internet is dramatically impacting on the services sector. This paper specifically investigates the relative impact of several forms of internet use on perceived performance for two groups of service organisations - retail service firms and professlonal health service firms. Using a mailed out self-administered questionnaire, 625 completed questionnaires were obtained and 43 per cent of respondents reported that they used the lternet. Thus the final usable sample in the study comprised 262 respondents. Results showed that the Internet does significantly influence perceived performance in both types of service firms. However,there are differences in the forms of lntemet use between the two service groups and their relative effect on performance. For retail firms, use of transactional function, such as ordering, selling and payment was found to be positively related to increases in perceived performance. In contrast, for professional health service firms, the ability to search for information on products and/or services was found to be positively associated with perceived performance. Finally, theoretical and managerial implications of the findings of this study are discussed.

Emerging strategies for sponsorship on the Internet

Internet sponsorship is a rapidly evolving communications platform at a fledgling stage for sponsorship-linked marketing. The complex and involving nature of the phenomena offers new research opportunities and the potential for innovative marketing strategies. The Internet presents the opportunity to combine aspects of traditional event/activity sponsorship and media sponsorship innovatively and to extend marketing strategy in new directions. This paper presents an overview of emerging Internet sponsorships strategies, identifies virtual and reality sponsorship opportunities, and explores emerging sponsorship extension strategies that relate to media, brand, channel development, consumer experience, and networking. Finally, future directions for researchers and practitioners are suggested.

Farmscape online : participatory design of internet meetings with farmers

This paper presents aspects of a longitudinal study in the design and practice of Internet meetings between farmer their advisors and researchers in rural Australia. It reports on the use of Microsoft NetMeeting (NM) by a group of agricultural researchers from Australia's CSIRO (Commonwealth Scientific and Industrial Research Organisation) for regular meetings, over nine years, with farmers and the commercial advisers. It describes lessons drawn from this experience about the conditions under which telecollaborative tools, such as NM and video conferencing, are likely to be both useful and used.

Leveraging sponsorships on the Internet: Activation, congruence, and articulation

This paper considers how the Internet can be used to leverage commercial sponsorships to enhance audience attitudes toward the sponsor. Definitions are offered that distinguish the terms leverage and activation with respect to sponsorship-linked marketing; leveraging encompasses all marketing communications collateral to the sponsorship investment, whereas activation relates to those communications that encourage interaction with the sponsor. Although activation in many instances may be limited to the immediate event-based audience, leveraging sponsorships via sponsors' Web sites enables activation at the mass-media audience level. Results of a Web site navigation experiment demonstrate that activational sponsor Web sites promote more favorable attitudes than do nonactivational Web sites. It is also shown that sponsorsponsee congruence effects generalize to the online environment, and that the effects of sponsorship articulation on audience attitudes are moderated by the commerciality of the explanation for the sponsor-sponsee relationship. Importantly, the study reveals that attitudinal effects associated with variations in leveraging, congruence, and orientation of articulation may be sustained across time.

Using the Internet to leverage sponsorships

This study considers the effectiveness of the Internet as a medium through which sponsorship investments can be leveraged. It considers the variables of sponsor-sponsee congruence,articulation, and the extent to which a sponsorship is leveraged via sponsor websites, in relation to consumer attitudes toward brand and company level variables across time. Results show that,consumer attitudes are more favourable for congruent sponsorships, those that are not articulated in commercially-oriented terms, and those that are leveraged via sponsor websites. Additionally, after a seven-day delay, leveraged sponsorships display sustained positive attitudes whereas those not leveraged display a decline in attitudes.

Now everything looks like a game : Mobile phones and location-based games.

This paper explores how we may transform peoples’ perceived access to cultural participation by exploiting the possible relationships between place, play and mobile devices. It presents SCOOT; a location-based game in order to investigate how aspects of game-play can be employed to evoke at once playful and culturally meaningful experiences of place. In particular this paper is concerned with how the portable, communicative and social affordances of mobile phones are integral to making a “now everything looks like a game” experience.

Maintaining human agency in the design on context-aware systems : Design games in a dental surgery

This paper describes a series of design games, specifically aimed at exploring shifts in human agency in order to inform the design of context-aware applications. The games focused on understanding information handling issues in dental practice with participants from a university dental school playing an active role in the activities. Participatory design activities help participants to reveal potential implicit technical resources that can be presented explicitly in technologies in order to assist humans in managing their interactions with and amidst technical systems gracefully.

Connecting brands with consumers on the internet

There is value of using brands to build relationships with customers and improve brand performance on the web. Products and services are easily replicated; therefore to simplify the buyer decision making process, brands have become important. Building strong brands is important as they can create contrasts between other brands, connections to consumers, and relevance through building customer relationships. Branding in an online environment is important for three reasons: security, recognition and associated costs.

Co-creating games: A co-evolutionary analysis

ABSTRACT. The phenomenon of consumer co-creation is often framed in terms of whether either economic market forces or socio-cultural non-market forces ultimately dominate. We propose an alternate model of consumer co-creation in terms of co-evolution between markets and non-markets. Our model is based on a recent ethnographic study of a massively multiplayer online game through its development, release and ultimate failure, and cast in terms of two explanatory models: multiple games and social network markets. We conclude that consumer co-creation is indeed complex, but in ways that relate to both emergent market expectations and the evolution of markets, not to the transcendence of markets.
