Recent development on distributed systems has shown that a variety of fairness constraints (some of which are only recently defined) play vital roles in designing self-stabilizing population protocols. Existing model checkers are deficient in verifying the systems as only limited kinds of fairness are supported with limited verification efficiency. In this work, we support model checking of distributed...
Transparency is crucial to ensuring fair, honest elections. Transparency is achieved by making information (e.g. election result) public. In e-voting literature, this publication is often described in terms of a bulletin board. While privacy of voting systems has been actively studied in recent years, resulting in various analysis frameworks, to date there has not been an explicit modelling of bulletin...
Privacy is a necessary requirement for voting. Without privacy, voters can be forced to vote in specific ways, and the forcing party can check their compliance. But offering privacy does not suffice: if a voter can reduce her privacy, an attacker can force her to do so. In this paper, we distinguish various ways that a voter can communicate with the intruder to reduce her privacy and classify them...
In voting, the notion of receipt-freeness has been proposed to express that a voter cannot gain any information to prove that she has voted in a certain way. Receipt-freeness aims to prevent vote buying, even when a voter chooses to renounce her privacy. In this paper, we distinguish various ways that a voter can communicate with the intruder to reduce her privacy and classify them according to their...
