AUTHENTICATION OF DIGITAL CERTIFICATES

V diplomskem delu obravnavamo infrastrukturo javnih ključev, digitalne podpise in digitalna potrdila. Predvsem se osredotočimo na načine overjanja digitalnih potrdil, njihove lastnosti, prednosti in slabosti. Poznamo tri načine overjanja, prvi je CRL, ki je najbolj enostaven. Sledi OCSP, ki je namenjen pridobivanju statusa v realnem času ter SCVP, ki je namenjen izdelavi in overjanju certifikacijskih poti. V sklopu diplomskega dela smo prav tako vzpostavili testno okolje za preverjanje digitalnih potrdil, ki vključuje Linux strežnik kot overitelja digitalnih potrdil in Javansko aplikacijo kot odjemalca.In this diploma work we described the public key infrastructure, digital signature and digital certificates.The main focus is on the 3 methods of validation.The first validation is with CRL\u27s which is the easyest. Second is OCSP, which is meant to get the status information in real time. The last one is SCVP validation, which is meant to construkt and validate certification paths. In this diploma work we also constructed a test environment for certificate validation, which is made out of a Linux server acting as a certificate auhtority and a client Java aplication
