  4. Classic Profile • Validity between 7 and 30 days • 7 day CRLs implies continuous issuance

  5. SLCS Profile • Validity between 3 days and ∞

  6. Issues seen • Netrust CRL of 1 day triggers many warnings • PMA warnings of actual invalidity are common • Unavailability fo CRL is on average 20% at any time • The CERN TCA CRL of 2 days hardly causes any actual problems • A warning once every few months • The CESNET CRL of 7 days causes no problems • Manual 30 day CRLs give incidental problems

  7. Proposal • Harmonize period between SLCS and Classic AP • at least 3 days before expiration • Only for on-line auto-generated CRLs • Manually generated CRLs and CRLs for off-line CAs stay at 7 days • Max life time for Classis AP stays at 30 days for issuing CAs
