Abstract

Samoupravljalna identiteta (SSI) predstavlja nov model identitete, ki spada med decentralizirane modele upravljanja digitalne identitete. Gre za koncept, ki si prizadeva zagotoviti večji nadzor in avtonomijo posameznikov nad lastnimi podatki in identiteto v digitalnem svetu. Varnostne težave so pomemben izziv pri razvoju SSI. Čeprav ta omogoča uporabnikom popolno avtonomijo nad njihovimi digitalnimi identitetami, obstaja tveganje za krajo osebnih podatkov ali vdor v digitalne denarnice. Poleg tega lahko napadalci izkoristijo ranljivosti v shranjevanju kriptografskih ključev in protokolih za šifriranje podatkov. Da bi rešili te težave, se razvijajo nove metode in protokoli za zagotavljanje varnosti in zasebnosti pri prenosu podatkov. V sklopu zaključnega dela smo izvedli analizo STRIDE, s katero smo naslovili nekaj pomembnejših varnostnih groženj, ki se lahko pojavijo med delovanjem sistema SSI. Prav tako smo razvili prototip rešitve, ki do določene stopnje omili identificirane varnostne težave in predlaga nov pristop pošiljanja preverljivih poverilnic med izdajateljem in imetnikom identitete.

Secondary title:	Ensuring security and privacy during a verifiable credential transfer
Secondary abstract:	Self-Soverign Identity (SSI) represents a new identity model that belongs to decentralized digital identity management models. It is a concept that strives to provide individuals with greater control and autonomy over their own data and identity in the digital world. Security issues are a major challenge in the development of SSI. Although SSI allows users full autonomy over their identities, there is a risk of data theft or hacking digital wallets. In addition, attackers can exploit vulnerabilities in cryptographic keys and data encryption protocols. To address these problems, new methods and protocols are being developed to ensure security and privacy in data transmission. As part of this work, we have carried out a STRIDE analysis to address some of the more important security threats that can arise during SSI operation. We have also developed a solution that mitigates the identified security issues to a certain extent and proposes a new approach for sending verifiable credentials between the issuer and the identity holder.
