IOS Press Remote Electronic Voting Using Verifiable Chain Encryption
- Thomas Tjøstheim; Geir Røsland
Abstract. In this paper, we describe a new remote electronic voting scheme. A probabilistic multiplekey encryption function based on an extension of ElGamal constitutes the cryptographic basis for the scheme. Ballot encryption, mixing, and tallying are carried out through the construction of verifiable chain encryptions. Verifiability is based on the use of publicly available bulletin boards and scrutinizers representing the different candidates (or parties). The proposed scheme is receipt free and applicable for large scale elections.

Electronic Restoration: Eliminating the Ravages of Time on Historical Maps
- German Diaz; Patricia Seed
Abstract. Geographic and mathematic analyses of historical maps require highly accurate adjustments to manuscripts in order to eliminate distortions caused by time and use. Earlier proposals for electronic restoration only offered effective solutions when compensating for tightly bound or straightly creased books. Applying a different solution, we have encountered a way of electronically restoring the map to its original shape, producing not only a more beautiful map, but also one suitable for further geographical analyses.

Receipt-Free Electronic Voting Scheme with a Tamper-Resistant Randomizer
- Tamper-resistant Randomizer; Byoungcheon Lee; Kwangjo Kim
We investigate the receipt-freeness issue of electronic voting protocols. Receipt-freeness means that a voter neither obtains nor is able to construct a receipt proving the content of his vote. [Hirt01] proposed a receipt-free voting scheme by introducing a third-party randomizer and by using divertible zero-knowledge proof of validity and designated verifier re-encryption proof. This scheme satisfies receipt-freeness under the assumption that the randomizer does not collude with a buyer and two-way untappable channel exists between voters and the randomizer.

Implementing electronic tendering for public works procurement - a Tasmanian experience
- Rundle, Andrew; Brewer, Graham; Gajendran, Thayaparan
Information and communication technology (ICT) applications, including electronic tendering (ET), have been introduced into public and private sector organisations business operations increasingly since the 1990’s. The uptake of ICT applications has extensively been based on the promise of streamlined business processes, increased competitiveness, and efficiencies in time and cost. As a Web based collaboration tool, electronic tendering processes have emerged in recent years as a procurement tool of great promise. The acclaimed benefits of ET are the ability to automate, streamline and enhance tendering processes, traditionally undertaken using paper-based methods. This paper reports findings from an exploratory study investigating the...

Perceived risk and trust associated with purchasing at Electronic Marketplaces
Understanding consumer behaviour is of vital importance to consumer oriented e-business models today. In this paper we study the relationships between consumer perceptions of risk and trust and the attitude towards purchasing at a consumer-to-consumer electronic marketplace. Typical for electronic marketplace settings is that consumer behaviour is subject to perceptions of the selling party as well as the institutional structures of the intermediary that is operating the electronic marketplace. Building upon the well-established literature of trust we consider the concepts of institutional trust and party trust. We extend this categorization by introducing the concepts of institutional risk and party risk....

Diffusion Of Electronic Commerce In Small And Medium Enterprises
- Robyn Lawson School; Robyn Lawson; Dr Carole Alcock; Professor Joan Cooper
Using the Internet for electronic business has become an area of action for the Australian Government. This paper presents research results from two regional areas which indicate that while most manufacturing SMEs use email, very few are involved in elecronic commerce activities. Major barriers are concern about security and privacy of transactions, cost of consultants, and lack of IT expertise of staff. Employing people with appropriate knowledge has been added to current training methods such as on-the-job training. Results from the two regional areas are found to be consistent. Comparisons between small and medium organisations highlight some differences.

Agent-Intermediated Electronic Markets in International Freight Transportation
- Barrie R. Nault; Albert S. Dexter
In many industries agent-intermediated markets are inefficient because information about latent demand and supply never gets to market. We demonstrate how information technology in the form of an agent-intermediated electronic market (EM) alleviates this problem by enhancing the agent-as-market-maker using the international freight transportation industry as an example. We find that an EM increases agent participation and investment thereby increasing demand and supply. Because of tradeoffs between incentives for investment the EM chooses a profit allocation between agents resulting in limited agent participation. In addition, when price depends on demand and supply balances, price and volume in the market can...

NormOriented Programming of Electronic Institutions: A Rule-based Approach
- A. García-camino; J. -a. Rodríguez-aguilar; C. Sierra
Norms constitute a powerful coordination mechanism among heterogeneous agents. We propose means to specify and explicitly manage the normative positions of agents (permissions, prohibitions and obligations), with which distinct deontic notions and their relationships can be captured. Our rule-based formalism includes constraints for more expressiveness and precision and allows the norm-oriented programming of electronic institutions: normative aspects are given a precise computational interpretation. Our formalism has been conceived as a machine language to which other higher-level normative languages can be mapped, allowing their execution.

Rapid mixing and security of chaum’s visual electronic voting
- Marcin Gomułkiewicz; Marek Klonowski; Mirosław Kutyłowski
Abstract. Recently, David Chaum proposed an electronic voting scheme that combines visual cryptography and digital processing. It was designed to meet not only mathematical security standards, but also to be accepted by voters that do not trust electronic devices. In this scheme mix-servers are used to guarantee anonymity of the votes in the counting process. The mix-servers are operated by different parties, so an evidence of their correct operation is necessary. For this purpose the protocol uses randomized partial checking of Jakobsson et al., where some randomly selected connections between the (encoded) inputs and outputs of a mix-server are revealed....
