Abstract

Ukratko, u ovom radu općenito smo opisali načine na koje se odvija elektroničko glasanje te kako se koriste elektronički sustavi za glasanje. U uvodu smo naveli prednosti koje ističu zagovornici te nedostatke na koje ukazuju protivnici elektroničkog glasanja. Nakon toga smo opisali kako su se razne tehnike koje se koriste u elektroničkom glasanju razvijale kroz povijest te zatim na koji način se određeni sustav koristi u nekim državama svijeta i u Republici Hrvatskoj. U nastavku smo pokazali primjenu matematike i kriptografije u elektroničkom glasanju. Osnovni cilj kriptografije je osiguravanje sigurne komunikacije između dvije strane, što se postiže tako da se tekst koji se šalje transformira u neki drugi tekst. Prvo smo naveli koje matematičke funkcije se koriste za preslikavanje određenih riječi, tj. transformaciju teksta. Zatim smo opisali neke metode elektroničkog glasanja kojima je cilj osigurati korektnost, povjerljivost, anonimnost korisnika i nemogućnost komuniciranja više osoba tijekom glasanja. U svakoj od tih metoda opisan je proces glasanja. U zadnjem poglavlju smo opisali tri sigurnosna protokola koja se mogu upotrijebiti u elektroničkom glasanju. U svakom od tih protokola opisan je način razmjene poruka sudionika te objašnjenje na koji način su sudionici sigurni da komuniciraju s pravom osobom. Poslije protokola "Infrastrukture javnog ključa" opisan je primjer tog protokola koji se koristi u praksi.

Abstract (english)

In this thesis, we have described the ways in which electronic voting is taking place and how electronic voting systems are used. In the introduction, we have highlighted the advantages pointed out by proponents and the disadvantages pointed out by opponents of electronic voting. After that, we have described how various techniques used in electronic voting have been developing through history, and then how a particular system is used in some countries of the world and in the Republic of Croatia. After that we have demonstrated the use of mathematics and cryptography in electronic voting. The main purpose of cryptography is to ensure secure communication between the two sides, which is achieved so that the text being sent is transformed into another text. Firstly, we have identified which mathematical functions are used to map certain words, that is, text transformation. Then we have described some electronic voting methods that aim to ensure correctness, verifiability, user anonymity and the receipt-freeness. In each of these methods we have described the voting process. In the last chapter, we have described three security protocols that can be used in electronic voting. Each of these protocols describes the way participants exchange their messages and explains how participants are sure to communicate with the right person. Following the ”Public Key Infrastructure” protocol, an example of this protocol used in practice is described.
