Abstract

Sa sve većim porastom računarstva u oblaku raste i potreba za sigurnim
skladištenjem podataka. Postoje mnoga rješenja koja pokušavaju osigurati
povjerljivost podataka u oblaku, a jedno od njih je CryptDB. CryptDB je
programsko rješenje koje pruža dokazivu i praktičnu privatnost u slučaju
kompromitiranog servera baze podataka ili znatiželjnih administratora. Za to koristi
šifriranu bazu, posredničkog poslužitelja i korisnički definirane funkcije. U ovom
radu obrađena su rješenja koja pokušavaju rješiti isti problem. Zatim je detaljno
objašnjen CryptDB i njegove funkcionalnosti, kao i kriptografski algoritmi korišteni
za njegovu implementaciju. Za praktični dio rada implementirano je rješenje po
uzoru na CryptDB, te su objašnjene glavne značajke rješenja, kao i razlike u
odnosu na CryptDB.

Abstract (english)

The constant growth of cloud computing services is also the reason for rising need for
safety of the data that is resting there. There are many solutions that try to provide
confidentiality of the data in the cloud, one of them being CryptDB. CryptDB is a
software solution that gives provides provable and practical privacy in the face of a
compromised database server or curious database administrators. The encrypted
database, proxy server and user defined functions are characteristics of the
solution. This thesis covers related work, then goes in depth on features and
cryptographic algorithms in CryptDB. In the practical part solution is implemented
inspired by CryptDB. Its main features are explained, as well as main differences
with CryptDB.
