PKI Components • • • CA server LDAP (or DAP) directory server Database for PKI Components • • • CA server LDAP (or DAP) directory server Database for CA records RA function Client/application software support

Basic Requirements • • Supported software (OS) and hardware PKCS standards supported? Interoperability with Basic Requirements • • Supported software (OS) and hardware PKCS standards supported? Interoperability with other PKIs CA hardware key storage support – what FIPS 140 -2 Level rating? – PKCS#11 and proprietary

CA hardware key storage • n. Cipher – (FIPS Level 3) • Safenet – CA hardware key storage • n. Cipher – (FIPS Level 3) • Safenet – (FIPS Level 2, 3) – (Data Key and Rainbow Tech subsidiaries – (Rainbow Tech bought Chrysalis) • AEP Networks – Keyper (FIPS Level 4) • Spyrus – LYNK (PCMCIA, USB) – Fortezza (PCMCIA)

Key Features 1 • Key sizes and types – at least 1024, >4096? RSA, Key Features 1 • Key sizes and types – at least 1024, >4096? RSA, DSA, Elliptic Curve • Dual key certificates? • Certificate profiles – prebuilt and customizable? – vendor key extensions? • Naming support: X. 500, DC naming • LDAP chaining or referrals, X 500, Active Directory • CRLs and/or OCSP

Key Features 2 • RA functions: online or off-line, self service • User interface Key Features 2 • RA functions: online or off-line, self service • User interface for CA and RA operators – Web Page or vendor software? • Key escrow and recovery – How much operator intervention required? • Record keeping (who has how many certs) and notifications (reminder of certs that need to be renewed) functionality

Key Features 3 • Interoperability with applications – Browser SSL, secure mail, signed documents, Key Features 3 • Interoperability with applications – Browser SSL, secure mail, signed documents, VPN, 802. 1 x EAP/TLS – OS smart card signon (MS requires special OIDs) • Client interface: Web Browser or vendor software – CSPs for MS IE • Client key storage – OS key store, PKCS#12 files, Vendor software, hardware tokens and smartcards

Key Features 4 • Issue server certificates – request types supported PKCS#10, CRMF. SPKAC(Netscape), Key Features 4 • Issue server certificates – request types supported PKCS#10, CRMF. SPKAC(Netscape), PKIX CMP, SCEP • CA can be interconnected with other PKIs – can be signed by recognized root certificates • (some vendors own well known roots) – can cross certify

Prices • In general a wide range, but decreasing • Models are either per Prices • In general a wide range, but decreasing • Models are either per seat or per certificate – per seat is important if your organization has a large turnover of individuals (like a graduating class) though the number of individuals may be relatively constant • Personal – $100 to $1 per seat – $70 to $7 per cert • Server $50 - $1000 • Other costs: annual maintenance or additional certificates
