1. Dartmouth PKI Update Robert Brentrup Internet2 Member Meeting April 21, 2004

2. Dartmouth PKI Lab R&D to make PKI a practical component of a campus network Dual objectives: –Deploy existing PKI technology to improve network applications (both at Dartmouth and elsewhere). –Improve the current state of the art. Identify security issues in current products. Develop solutions to the problems. Sponsored by the Mellon Foundation, Intenet2/AT&T, NSF, DHS, Cisco, HP Labs, IBM Research

3. PKI Implementation Commercial CA Software (Sun/iPlanet) Sun 250 server Single Online CA Server –Hardware Key Storage –Dedicated Firewall –Publishes CRLs and provides OCSP

4. LDAP Directory Maintained from Institutional Systems –SIS, HR, Sponsored Guests Automated Addition and Deletion CA Publishes Certificates and CRLs to LDAP
