Izdavanje prvog sertifikata • Videti instrukcije na http://aegis-ca.rcub.bg.ac.yu/ • Formirati PKCS#10 zahtev – najlakše je na nekom od AEGIS UI računara • Poslati zahtev i lične podatke (ime i prezime, e-mail, institucija, adresa) preko AEGIS CA web interfejsa ili na aegis-ca@aegis-ca.rcub.bg.ac.yu. • Generiše se slučajni 10-ocifreni broj i šalje automatski e-mail odgovor gde se korisnik obaveštava • Da je vreme procesiranja sertifikata 3 radna dana • Da je potrebno da se lično pojavi u kancelarijiAEGIS CA ili RA radi potvrde identiteta • O adresi i brojevima telefona AEGIS CA/RA • O procesu autentifikacije korisnikovog e-mail-a: generisani broj se deli na dva dela. U odgovoru se nalazi prvih 5 cifara, dok drugih 5 korisnik dobija kada se pojavi radi autentifikacije. • Korisnik dolazi kod AEGIS CA ili RA sa validnim dokumentom za ličnu identifikaciju i dokazom veze sa institucijom navedenom u zahtevu. • Šalje 10 cifara sa prijavljene e-mail adrese na e-mail AEGIS CA/RA • Na ovako potvrđenu e-mail adresu se dostavlja potpisan sertifikat • Korisnik se obaveštava da treba da u roku od 5 dana pošalje e-mail potpisan dobijenim sertifikatom kojim prihvata svoj novi sertifikat i CP/CPS dokumenat • Korisnik svoj sertifikat može koristiti za pristup Grid-u, za potpisivanje e-mail-ova, autentifikaciju preko Web-a i enkripciju podataka.

Izdavanje narednih sertifikata • Zahtevi za re-key sertifikata koji su potpisani važećim sertifikatom izdatim od CA akreditovanim od EUGridPMA će biti potpisani bez prethodne procedure jer je identitet korisnika već utvrđen. • Korišćeni sertifikat i zahtev treba da se odnose na istu osobu, e-mail i instituciju. • CA/RA i dalje mora da proveri da li osoba ima vezu sa institucijom navedenom u zahtevu – dovoljno je da je e-mail institucionalni. AEGIS 2007 Annual Assembly
Generisanje sertifikata i sigurnost • Sertifikati se generišu na izolovanom računaru, u kancelariji sa ograničenim pristupom. • Koriste se lozinke od bar 15 karaktera. CA manager i CA operater jedini znaju root password. • Na računaru je instaliran CentOS operativni sistem sa minimumom servisa - apliciraju se sve security zakrpe. Koristi se CSP softver. • Računar ima CD-RW uređaj i USB konektore za backup. • Hard disk se stavlja u HDD rack, čuva se na sigurnoj lokaciji. • Vrši se backup na CD-ROM i USB flash-u koji se takođe čuvaju sigurnoj lokaciji. Postojaće i off-site backup. • Na CA sajtu će biti omogućena isključivo pretraga (ne i listanje) izdatih sertifikata. • Čuva se lista generisanih sertifikata. • Kada se sertifikat povuče, obnavlja se CRL, koja se odmah objavljuje na CA sajtu. CRL se takodje obnavlja na svakih 30 dana, bez obzira da li je bilo povučenih sertifikata. AEGIS 2007 Annual Assembly
