Online voting is a trend that is gaining momentum in modern society. It has great potential to
decrease organizational costs and increase voter turnout. It eliminates the need to print …

A blockchain is a distributed, digitized and consensus-based secure information storage
mechanism. The present article provides an overview of blockchain based e-voting systems …

We introduce a model for electronic election schemes that involves a more powerful
adversary than previous work. In particular, we allow the adversary to demand of coerced …

We present a linkable spontaneously anonymous group (LSAG) signature scheme
(alternatively known as linkable ring signature scheme) satisfying the following three …

Cryptographic techniques are employed to ensure the security of voting systems in order to
increase its wide adoption. However, in such electronic voting systems, the public bulletin …

We present a receipt-free voting scheme based on a mix-type anonymous channel [Cha81,
PIK93]. The receipt-freeness property [BT94] enables voters to hide how they have voted …

The Schnorr blind signing protocol allows blind issuing of Schnorr signatures, one of the
most widely used signatures. Despite its practical relevance, its security analysis is …

We present a mathematical construct which provides a cryptographic protocol to verifiably
shuffle a sequence of k modular integers, and discuss its application to secure, universally …

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 …

Voting schemes that provide receipt-freeness prevent voters from proving their cast vote,
and hence thwart vote-buying and coercion. We analyze the security of the multi-authority …
