Abstract:Metode deljenja skrivnosti so kriptografske metode, ki s posebnimi postopki skrivnost razdelijo na deleže. Iz dovolj velike podmnožice teh deležev lahko nato izračunamo začetno skrivnost, medtem ko premajhna množica deležev ne izda nobene informacije o skrivnosti. V magistrskem delu smo opisali in implementirali tri različne metode deljenja skrivnosti, ki delujejo nad poljubnimi podatki, uporabne pa so tudi za poraz deljeno računanje, avtorizacijo z več udeleženci ipd. Pri testiranju se je ena izkazala za preveč počasno, drugi dve pa brez težav delujeta na manjših količinah podatkov. Na koncu smo napisali še preprosto spletno aplikacijo, ki prikazuje primer varnega izračuna deležev, hranjenja in rekonstrukcije skrivnosti.

Title:Secret sharing methods
Abstract:Secret sharing methods are cryptographic methods which divide a given secret into shares. The initial secret can then be reconstructed with a large enough subset of these shares, while a too small set provides no useful information about the secret. These methods can also be used in distributed computing and authorization which requires the cooperation of multiple entities. Three different methods were implemented, which can be used on any kind of data. When testing these methods, it turned out that one of the methods was too slow to be useful for bigger amounts of data, while the remaining two worked smoothly. In the end a simple web application was written, which shows how to safely distribute shares, store them and reconstruct the secret.
