To provide universal verifiability, cryptographic voting protocols often require a broadcast channel to spread the election data to the public. The basic requirements on such a broadcast channel are similar for most protocols, for example that the ch

In this paper, we propose further performance improvements for Wikstrom’s shuffle proof. Compared to an implementation based on general-purpose exponentiation algorithms, we show that the overall shuffle operation can be accelerated by approximatel

Modern web applications using advanced cryptographic methods may need to calculate a large number of modular exponentiations. Performing such calculations in the web browser efficiently is a known problem. We propose a solution to this problem based

The publication of the election data is fundamental for making electronic voting systems universally verifiable. For this, voting protocols usually rely on a secure bulletin board, which keeps track of the data produced during the protocol execution.

In this paper, we analyze the process of performing the universal verification of an electronic election. We propose a general model of the election process and define the data flow into the verification process. We also define the purpose and outcom

Implementing the shuffle proof of a verifiable mix-net is one of the most challenging tasks in the implementation of an electronic voting system. For non-specialists, even if they are experienced software developers, this task is nearly impossible to

In this paper, we propose a new method for cast-as-intended verification in remote electronic voting. We consider a setting, in which voters receive personalized verification code sheets from the authorities over a secure channel. If the codes displa

This paper presents a generic approach to prevent board flooding attacks in remote electronic voting schemes providing coercion-resistance. A key property of these schemes is the possibility of casting invalid votes to the public bulletin board, whic
