+Porazdeljene razpršilne tabele (angl.
+ distributed hash table) so razpršilne tabele, ki podatke, ponavadi so to
+ dokumenti, strukturirani kot vrednost in njen pripadajoč ključ, hranijo
+ distribuirano na več vozliščih, kjer se podatki shranjujejo.
+ V računalniških sistemih se DHT uporablja za hrambo podatkov v omrežjih
+ P2P (angl.
+ peer to peer), kjer se podatki vseh uporabnikov enakomerno porazdelijo
+ med vozlišča in so tako decentralizirani in preprosto dostopni članom omrežja.
+ Ker se podatki izmenjujejo znotraj omrežja na vozliščih, ki z izvorom in
+ destinacijo podatkov niso povezani, jih lahko vozlišča v velikih količinah
+ shranjujejo.

+\begin_layout Standard
+V raziskovalni nalogi je preverjena praktična zmožnost pridobivanja velike
+ količine podatkov v omrežju BitTorrent za P2P izmenjavo datotek, pridobljeni
+ podatki pa so analizirani.
+ Vsaka poizvedba po seznamu imetnikov datotek vsebuje ključ podatka v DHT
+ in se prenese preko okoli

+ vozlišč, kjer je
+\begin_inset Formula $n$
+\end_inset
+
+ število vseh uporabnikov v omrežju.
+ Ker vsaka poizvedba obišče tako veliko število vozlišč, lahko eno vozlišče
+ prejme veliko obstoječih ključev v omrežju, s katerimi si lahko prenese
+ metapodatke v omrežju BitTorrent.
+\end_layout

+\begin_layout Standard
+Naloga se osredotoči na pridobivanje metapodatkov v omrežju BitTorrent,
+ glede prenosa datotek, ki jih ponujajo računalniki, pa se vsled njihove
+ velikosti ne opredeli.
+ Metapodatki konceptualno sicer niso shranjeni v DHT (namesto metapodatkov
+ o datotekah so v omrežju shranjeni seznami računalnikov, od katerih si
+ metapodatke lahko prenesemo), vendar odkrivanje njihovega obstoja omogoči
+ DHT.

+\begin_layout Standard
+Distributed hash tables are hash tables that store data, usually documents,
+ structured by key-value association, distributed amongst many nodes, where
+ they are kept for longer periods of time.
+ In computer networks are DHTs used for data storage in peer-to-peer networks,
+ where common data are evenly distributed amongst nodes.
+ Consequentially are those data stored in a decentralized manner and are
+ accessible to every node in the network with low complexity.
+ Because the data are exchanged across nodes that are neither source or
+ destination of a datum, they can obtain new data and store them in large
+ quantities.
+\end_layout
+
+\begin_layout Standard
+A practical possibility of harvesting large amounts of data in BitTorrent
+ network for peer-to-peer file transfer is presented and harvested data
+ are analyzed.
+ Every query for file providers contains the key for the queried-for list
+ and traverses over around
+\begin_inset Formula $\log_{2}n$
+\end_inset
+
+ n nodes, where n means the number of participants in the network.
+ Because every query visits such a large amount of nodes, can every node
+ receive a large amount of existing keys in the DHT that can be used for
+ downloading metadata of BitTorrent files.
+\end_layout
+
+\begin_layout Standard
+This research paper focuses solely on harvesting metadata, not on downloading
+ shared files, primarily due to their extreme size.
+ Metadata conceptually aren't stored in the DHT (instead of file metadata,
+ lists of computer addresses, from which metadata can be downloaded, are
+ stored), but the DHT enables their discovery.
