Analysis of electronic and telematic voting systems in binding experiences

This paper is about analysis and assess of three experiences on telematic and electronic voting dealing with such aspects as security and achievement of the social requirements. These experiences have been chosen taking into account the deepness of the public documentation and the technological challenge they faces.

Use of Java Cards in a telematic voting system.

This paper presents a general view of the telematic voting system developed by its authors, with a special emphasis on the important role that smart cards play in this scenario. The use of smart cards as basic pieces for providing secure cryptographic operations in this type of voting scheme is justified. The differences and advantages of Java Cards in comparison with the ?classical? smart cards (those that completely conform to the ISO/IEC 7816 standard) are also discussed. As an example, the paper describes one of the applets implemented in the voting Java Card as part of the general telematic voting application.

VOTESCRIPT: Telematic voting system designed to enable final count verification

In this paper we present a global description of a telematic voting system based on advanced cryptography and on the use of smart cards (VOTESCRIPT system) whose most outstanding characteristic is the ability to verify that the tally carried out by the system is correct, meaning that the results published by the system correspond with votes cast. The VOTESCRIPT system provides an individual verification mechanism allowing each Voter to confirm whether his vote has been correctly counted. The innovation with respect to other solutions lies in the fact that the verification process is private so that Voters have no way of proving what they voted in the presence of a non-authorized third party. Vote buying and selling or any other kind of extortion are prevented. The existence of the Intervention Systems allows the whole electoral process to be controlled by groups of citizens or authorized candidatures. In addition to this the system can simply make an audit not only of the final results, but also of the whole process. Global verification provides the Scrutineers with robust cryptographic evidence which enables unequivocal proof if the system has operated in a fraudulent way.

Contributions to traditional electronic voting systems in order to reinforce citizen confidence

This document provides a general description of the telematic voting scenario designed by the author?s research group. This scenario reinforces verification procedures as key elements to achieve full acceptance of the system on the part of voters. To frame this work, a general overview of electronic voting is given and the conditions entailed by these systems are specified.

Sophisticated security verification on routing repaired balanced cell-based dual-rail logic against side channel analysis

Conventional dual-rail precharge logic suffers from difficult implementations of dual-rail structure for obtaining strict compensation between the counterpart rails. As a light-weight and high-speed dual-rail style, balanced cell-based dual-rail logic (BCDL) uses synchronised compound gates with global precharge signal to provide high resistance against differential power or electromagnetic analyses. BCDL can be realised from generic field programmable gate array (FPGA) design flows with constraints. However, routings still exist as concerns because of the deficient flexibility on routing control, which unfavourably results in bias between complementary nets in security-sensitive parts. In this article, based on a routing repair technique, novel verifications towards routing effect are presented. An 8 bit simplified advanced encryption processing (AES)-co-processor is executed that is constructed on block random access memory (RAM)-based BCDL in Xilinx Virtex-5 FPGAs. Since imbalanced routing are major defects in BCDL, the authors can rule out other influences and fairly quantify the security variants. A series of asymptotic correlation electromagnetic (EM) analyses are launched towards a group of circuits with consecutive routing schemes to be able to verify routing impact on side channel analyses. After repairing the non-identical routings, Mutual information analyses are executed to further validate the concrete security increase obtained from identical routing pairs in BCDL.

Identification of voting systems for the identification of preferences in public participation. Case Study: application of the Borda Count system for collective decision making at the Salonga National Park in the Democratic Republic of Congo.

Abstract:The aim of this paper is to review the literature on voting systems based on Condorcet and Borda. We compared and classified them. Also we referred to some strengths and weaknesses of voting systems and finally in a case study, we made use of the Borda voting system for collective decision making in the Salonga National Park in the Democratic Republic of Congo. Resumen: el objetivo de este trabajo es hacer una revisión bibliográfica de los sistemas de votación basados en Condorcet y Borda. Se ha comparado y clasificado los mismos. Así mismo se ha hecho referencia a algunas debilidades y fortalezas de los sistemas de votación y por último en un caso de estudio, se ha hecho uso del sistema de votación de Borda para la toma de decisión colectiva en el Parque Nacional de Salonga en la República Democrática del Congo.
