— The United Kingdom (UK) government has repeatedly expressed a desire to employ a Remote Electronic Voting (REV) system in a general election after 2006. Most existing REV schemes employ some form of cryptography, either to secure transmission of votes, or to model some desirable feature of public elections. This paper outlines the limitations of employing… (More)
Remote electronic voting is currently being piloted in the UK as a means of increasing the convenience of casting a ballot, which it is hoped will be reflected in an increased participation in elections. Most proposed electronic voting schemes envisage the use of cryptography in order to model the features of democratic elections, which, informally, include… (More)
— Recent controversy regarding reforms to the voting system cast doubt on the likelihood of deploying electronic voting systems in the near future. This paper notes the deficiencies in the approach to requirements for electronic voting in general and outlines some of the recent developments in electronic voting technologies in the UK.
Virtual Worlds are an important tool in modern education practices as well as providing socialisation, entertainment and a laboratory for collaborative work. This paper focuses on the uses of virtual worlds for education and synthesises over 90 published academic papers, reports and educational websites from around the world. A taxonomy is then derived from… (More)
This paper addresses support for energy efficient single-hop communications in Environmental Monitoring Wireless Sensor Networks (WSN). The main contributions are twofold firstly; the identification of scenarios where single hop communication, between multiple sensors and a base station is both feasible and offers benefits with respect to power… (More)
Wireless Sensor Networks were first used in military missions. They are currently deployed in a wide range of civil applications as sensors are becoming smaller and cheaper. The main limitation is the energy constraint as it seems impractical to change or recharge the battery. Several applications require an end-to-end reliable data transport with… (More)
To allow testers to know the types of faults they are looking for and to detect fault commonality and criticality, it is important to categorise code defects. The paper reviews testing techniques and taxonomies and considers fault clustering and isolation.
This paper describes an exploratory study of a prototype implementation of a pollsterless remote voting scheme, mCESG. The aim of the study was to investigate voter attitudes towards the system in general, with particular interest in the pollsterless vote verifiability provided. Although the focus of the study was one particular prototype system, the… (More)
The advances made in technology have unchained the user from the desktop into interactions where access is anywhere, anytime. In addition, the introduction of ubiquitous computing (ubicomp) will see further changes in how we interact with technology and also socially. Ubicomp evokes a near future in which humans will be surrounded by " always-on, "… (More)
