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)
— 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.

— 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.
— Over the past several years, the UK Government has piloted several new voting technologies during local authority elections. The mCESG pollsterless Remote Electronic Voting (REV) system, which was designed with the UK electoral context in mind, is described in detail in . Here, we describe two variations to the mCESG scheme which (a) improve its… (More)
—Predicate Based Encryption (PBE) is a novel family of public key encryption schemes that allows for expressive, and fine-grained, access control to be integrated within the cryptographic process. Providing an efficient means to realise distributed encrypted access control. Security patterns allow for security problems and their solutions to be described… (More)
