Abstract
Glavni cilj ovog rada je provjera koncepta upotrebe blockchaina za registraciju i evidentiranje događaja u stvarnom vremenu na siguran način uz mogućnost korištenja kombinacija ključeva za pristup evidentiranim podacima. Rad započinje kratkim opisom blockchaina, Ethereuma i kriptografije, a samim time i njihovih ograničenja. Na temelju karakteristika opisanih u prvim poglavljima rada dolazimo do zaključka da je blockchain potpuno transparentan te je stoga implementacija šifriranja gotovo nemoguća. Međutim, napretkom koncepata poput dijeljenja tajni i homomorfnog šifriranja, nemogućnost šifriranja na blockchainu postaje upitna. Budući da implementacija prethodno navedenih koncepata još nije zaživjela, praktični dio ovog rada fokusira se na implementaciju dijeljenja tajni i šifriranja kombinacijom ključeva izvan blockchaina okruženja. Osim što omogućuje šifriranje i pohranu vrijednosti na blockchain, ovakva implementacija pruža i mogućnost dohvata i dešifriranja zapisanih podataka.
Abstract (english)
The primary aim of this thesis is to explore the possibility of applying the concept of multisignature encryption to blockchain. The paper opens with a brief description of the current features of blockchain, Ethereum and cryptography and, by implication, their limitations. Taking into account these features, which are explained in the first chapters of this paper, it seems fair to conclude that blockchain is completely transparent, hence the difficulty of implementing multisignature encryption as such. However, due to advances in secret sharing and homomorphic encryption, the impossibility of applying multisignature encryption to block chain has been thrown in to question. Given the fact that the above-mentioned mechanisms are yet to be implemented,the practical part of this paper illustrates an alternative approach which allows the off-chain implementation of secret sharing and multisignature value encryption. Such an approach not only enables the storage of data on the Ethereum blockchain, but also makes it possible to read and decrypt the aforementioned data.
