Abstract

Spajanjem mnogih osjetljivih infrastruktura na internetsku mrežu dovelo je do potrebe za
stvaranjem sigurnijeg rada protokola usmjeravanja. U ovom završnom radu predstavljaju se
najčešći protokoli usmjeravanja (BGP, OSPF, RIP), njihove karakteristike i načini rada. S
obzirom da za svoj prvobitan rad nisu imali potrebu za sigurnosnim mehanizmima sada su
najčešća meta napada pa se tako ovaj završni rad bavi i najčešćim vrsta napada. Kao rješenje,
ovaj rad predstavlja tri sigurnosna mehanizma protokola usmjeravanja: jednosmjerni lanac s
potvrdom stabla, jednosmjerni MW lanac i lance hash stabla. Sigurnosni mehanizmi temelje se
na poznatim kriptografskim mehanizmima i ovaj rad će dati uvid u mehanizme Merkleovog
stabla i jednosmjernog hash lanca.

Abstract (english)

Connecting of many sensitive infrastructures to the internet has led to the need to create more
secure routing protocols. This paper introduce the most common routing protocols (BGP, OSPF,
RIP), their characteristics and modes of operation. Since they did not need security mechanisms
for their original work, they are now the most common target of attacks, so this paper deals with
some of the most common types of attacks. As a solution, this present three routing protocol
security mechanisms: tree authenticated one-way chains, the MW-chain, and hash tree chains.
Security mechanisms are based on known cryptographic mechanisms and this paper will provide
insight into the mechanisms of the Merkle tree and one-way hash chain.
