Abstract
V diplomski nalogi je predstavljen digitalni plačilni sistem Bitcoin. Opisana je kriptografija, na kateri je sistem zasnovan. Predstavljeno je delovanje in kratka zgodovina sistema. Večji poudarek je na oceni anonimnosti pri plačevanju z Bitcoinom in na zagotavljanju varnosti pri izvedbi transakcij. V sklopu anonimnosti je opisan nivo prikrivanja identitete, ki ga zagotavlja sistem in dodatni mehanizmi in opozorila, ki so potrebni za anonimno plačevanje. V sklopu varnosti so naštete potencialne ranljivosti sistema Bitcoin, izpostavljena je šibka točka pri sprejemanju hitrih plačil, ki napadalcem omogoča izvedbo tako imenovanega double-spending napada. Praktično je prikazano, kako je možno brez posebnih orodij z odprtokodno programsko opremo, ki jo razvija Bitcoin skupnost sama, izvesti napad.

Title:Security and Anonymity of Bitcoin Payments
Abstract:
This thesis presents the digital payment system Bitcoin. It describes the cryptography on which the system is based. Presented are the short history of the system and the principles of how it works. Highlighted are the state of anonymity that the system provides while making payments and the safety it guarantees while executing transactions. Within the context of anonymity, the state of masking the users identity within the payment system is described, together with warnings and mechanisms to better hide the users identity. Considering the safety of Bitcoin transactions, potential vulnerabilities of the system are listed. Exposed is a weakness, while accepting fast payments, that enables attackers the execution of the double-spending attack. Practically it is demonstrated, how to execute the attack without special tools, with the use of opensource software recomended and developed by the Bitcoin community.

Keywords:Bitcoin, anonymity, double-spending
