20.500.12556/RUL-87034 Varnost podatkov v oblaku Security of Data Stored in the Cloud 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. 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. oblak varnost kriptografija kriptosistemi funkcionalni kriptosistemi homomorfni kriptosistemi šifriranje na osnovi atributov in predikatov cloud security cryptography cryptosystem functional encryption homomorphic encryption attribute based encryption true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-11-16 14:36:51 2016-11-16 14:36:51 2022-08-09 11:00:03 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 18185 Vrhovec_Andraz_-_Varnost_podatkov_v_oblaku.pdf Vrhovec_Andraz_-_Varnost_podatkov_v_oblaku.pdf 1 0398C7F76F586AFEEEC8BBE64E2B3D65 09b2937ea233a5b401cbb165979451278e1229f13a2c21af2a900f3e27f0befa 14f4af38-a1b1-11eb-a523-00155dcfd717 20.500.12556/rul/96441550-60d8-42ef-a49b-09b71b3f4aa5 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=90379 Fakulteta za računalništvo in informatiko 0 0 0
