Abstract
Digitalni potpisi služe kako bi zaštitili poruku od neželjenih izmjena kroz kanal i kako bi posvjedočili da je pošiljatelj doista ona osoba koja to i tvrdi. U svojoj infrastrukturi, sustav digitalnog potpisivanja koristi princip kriptografije s javnim ključem i digitalne certifikate. Najčešći algoritmi za implementaciju digitalnih potpisa jesu RSA, DSA i ECDSA. RSA i DSA se temelje na problemu faktorizacije velikih brojeva, a ECDSA na eliptičkim krivuljama. Općenito, za istu duljinu ključa, ECDSA algoritam je efikasniji od algoritama koji se zasnivaju na problemu faktorizacije velikih brojeva. Postoji nekoliko vrsta napada na algoritme digitalnog potpisivanja od kojih su najčešći napadi mjerenjem vremena i napadi usmjereni na maskirnu vrijednost poruke. Algoritmi za digitalno potpisivanje se primjenjuju za potpisivanje dokumenata, za slijepo potpisivanje, potpisivanje internetskih stranica i sadržaja na njima te za potpisivanje multimedijalnih sadržaja. Očekuje se da će digitalni potpisi u budućnosti potpuno zamijeniti ručno potpisivanje.
Abstract (english)
Digital signatures provide protection to the messages from unwanted changes through the channel and testify that the sender is really the person who claims it. In its infrastructure, the digital signature system uses the principle of public key cryptography and digital certificates. The most common algorithms for implementing digital signatures are RSA, DSA and ECDSA. RSA and DSA are based on the problem of factorization of large numbers, and ECDSA on elliptic curves. Generally, for the same key length, the ECDSA algorithm is more efficient than algorithms based on the problem of factorization of large numbers. There are several types of attacks on digital signature algorithms, most commonly being timing attacks and attack based on the message padding value. Digital signature algorithms apply to signing documents, blind signing, signing up of websites and content on them, and signing up for multimedia content. It is expected that manual signatures in the future will be completely replaced by digital signatures
