  2. UT Topology • 16 physical institutions of higher learning • 1 virtual institution • All element operated independently • In most cases, the institutions are geographically dispersed throughout Texas • All institutions issue identity certificates as intermediate CA under the Verisign Public Root

  3. Current PKI Uses • System Wide SMIME signature • Houston specific uses • SMIME signing and encryption • Strong A&I for 3 tier web applications • Student Grades, Resident evaluations, LDAP Group management, CPHS, and many many others…… • VPN • Wireless Access (soon)

  4. Commitments to PKI • UT System wide publicly rooted PKI in its 5th year • Additional opportunities for use / expansion • Hippa • Events that exposed security weakness in a public venue

  5. Collaboration Opportunities in Texas • The University of Texas • Inter/Intra Institutional • Within the Texas Medical Center-Houston • Inter-Institutional • Outside the Texas Medical Center • Intra-Institutional

  6. UT CollaborationsInter/Intra-Institutional • UT Information Security (UT InfoSec) • Driving PKI requirements • IT Security • Hippa (TAC 202 Lite) • Texas Administrative Code 202 • Satellite Campuses • UT Houston School of Public Health • UT Houston School of Nursing

  7. TMC Collaborations • Graduate Medical Evaluations • Student Exchange programs • UT, Rice, U of H, A&M, Baylor, Houston CC • Adjunct Faculty from other institutions • MDACC, TCH, THI, TIRR, Methodist, St. Luke’s, Shriner’s, U of H, Private MDs

  8. Today UT, Tomorrow ? • 3 Tier Web based courses and applications • Cardio Physiology • Neurobiology and Anatomy • Blackboard • GMEDS • CPHS (possibly strong A&I) • Helping Research and Security coexist • Shared Library Resources

  9. SHIB & PKI • PKI as needed for authentication • Target presents requirements for strong authN • Users present UT/Verisign rooted certs to the Shib HS • HS validates cert, queries LDAP for existence of user in the directory and creates opaque handle etc…. • AA releases user’s credentials to target as required • Shibboleth for authorization in the usual way • Standardizing Identity Verification within UT via the same CP/CPS • Boilerplates for bilateral agreements for Shibboleth Clubs / or UT Federation in terms of Target applications
