Varnost podatkov v oblaku

VRHOVEC, ANDRAŽ (author), Jurišić, Aleksandar (mentor)

Cilj te diplomske naloge je predstaviti pregled varnosti podatkov, ki jih zaupamo oblačnim sistemom. V prvem delu se posvetimo osnovnim definicijam oblaka in varnosti ter identificiramo nekatera varnostna tveganja, ki se pojavijo ob uporabi oblaka. Drugi del se posveča kriptografiji, predvsem šifriranju, kot orodju za zagotavljanje varnosti podatkov v oblaku. Na poljuden način poskusimo predstaviti nekaj novih idej v kriptografiji, ki so se pojavile šele pred kratkim in so zelo zanimive za uporabo v oblaku. Za konec podamo še nekaj nasvetov, kako poskrbeti za varnost podatkov.

• Title: Security of Data Stored in the Cloud

Abstract

The goal of this diploma thesis is to give an overview of data security in cloud systems. The first part covers basics of cloud and security. Additionally it identifies some risks arising from the use of cloud computing. The second part focuses on cryptography, especially on ciphers, as a tool for mitigation of those risks. We try to convey some recent ideas (especially those interesting in the context of cloud computing) from the cryptographic world to the reader in an easy manner. We conclude with some tips on how to ensure security of data.
