Abstract
U ovom radu obrađena je tema Paillierovog kriptosustava i njegova primjena. Opisani su kriptosustavi s javnim ključem i homomorfni sustavi. Homomorfni sustavi se dijele na djelomične i potpune, a ono što ih obilježava je izvršavanje različitih algebarskih operacija kao što su zbrajanje i množenje nad šifriranim podacima bez njihovog prethodnog dešifriranja. Zbog toga je homomorfna enkripcija zanimljiva u sustavima koji imaju potrebu za obradom informacija za koje je nužno da ostanu... More sigurni. Paillierov kriptosustav je opisan kroz tri glavna koraka, a to uključuje generiranje ključeva, šifriranje i dešifriranje informacija. Također, opisana su i njegova svojstva aditivnog i multiplikativnog homomorfizma. Uspoređen je s drugim poznatijim djelomičnim homomorfnim sustavima te je ukratko dan pregled mogućih poboljšanja. Na kraju su navedene neke moguće primjene. U sklopu zadatka izrađena je i implementacija u Python programskom jeziku te je napravljena analiza učinkovitosti različitih dijelova kriptosustava. Less
Abstract (english)
This thesis studies the topic of the Paillier cryptosystem and its applications. Public key cryptosystems and homomorphic systems are described. Homomorphic systems can be grouped into partial and fully homomorphic schemes, and what characterizes them is the execution of various algebraic operations such as addition and multiplication over encrypted data without their prior decryption. It is therefore interesting in systems that must process information that is necessary to remain... More secure. Paillier’s cryptosystem is described through three main components: key generation, encryption, and decryption of information. In addition, its properties of additive and multiplicative homomorphism are described. It has been compared with other more well-known partial homomorphic schemes, and an overview of possible improvements is given. Finally, some possible applications are listed. As a part of the research, implementation in Python was made with an analysis of the efficiency of different parts of the cryptosystem. Less
