In this paper, we present the user evaluation results of a Community-centric Music Voting service that relies on a DHT-based P2P network. For each user community, an independent DHT-overlay is established. These separate DHT-overlays are then connected to specific commercial premises or larger areas. A user evaluation was conducted in a real usage environment, where the user communities were co...

We present new results in the areas of cryptography and voting systems. 1. Pattern matching encryption: We present new, general definitions for queryable encryption schemes – encryption schemes that allow evaluation of private queries on encrypted data without performing full decryption. We construct an efficient queryable encryption scheme supporting pattern matching queries, based on suffix t...

Malicious software (malware) represents a threat to the security and the privacy of computer users. Traditional signature-based and heuristic-based methods are inadequate for detecting some forms of malware. This paper presents a malware detection method based on supervised learning. The main contributions of the paper are two ensemble learning algorithms, two pre-processing techniques, and an ...

The Norwegian government is planning trials of internet voting in the 2011 local government elections. We describe and analyse the cryptographic protocol that will be used. In our opinion, the protocol is suitable for trials of internet voting, even though it is not perfect. This paper is a second step in an ongoing evaluation of the cryptographic protocol.

In this paper we present preliminary findings of a case study analysing the implementation experience with Internet voting in Austrian academic tests and one election. The project identified a first set of six building blocks which seem important for the conduct of Internet voting, which include legal basis, identification, secrecy, transparency, control, and evaluation.

Do print media significantly impact political attitudes and party identification? To examine this question, we draw on a rare quasi-natural experiment that occurred when The Sun, a right-leaning UK tabloid, shifted its support to the Labour party in 1997 and back to the Conservative party in 2010. We compared changes in party identification and political attitudes among Sun readers with non-rea...

We generate synthetic elections using two sources of survey data, two spatial models, and two standard models from the voting literature, IAC and IC. For each election that we generate, we test whether each of 54 voting rules is (1) non-manipulable, and (2) efficient in the sense of maximizing summed utilities. We find that Hare and Condorcet-Hare are the most strategy-resistant non-dictatorial...

Civitas is the first electronic voting system that is coercion-resistant, universally and voter verifiable, and suitable for remote voting. This paper describes the design and implementation of Civitas. Assurance is established in the design through security proofs, and in the implementation through information-flow security analysis. Experimental results give a quantitative evaluation of the t...

Voting is an important part of the democratic process. The electorate makes a decision or expresses an opinion that is accepted for everyone. Some parts could be interested in the election results deviation without anyone else noticing it. However, ensuring that the whole voting process is performed correctly and according to current rules and law is, then, even more important. We present in th...
