Outline of PKI technology PKI - Acronym for Public Key Infrastructure Confidentiality Authenticity Integrity Non-repudiation The Infrastructure portion of PKI

Why UW-Madison uses PKI HIPAA FERPA Research activities Open network Higher education PKI partners Help and learn from Internet2, Educause and CIC

UW-Madison PKI Activity 2002 – Present Provided Digital Certs to Shibboleth Testing Community Spring - 2005 Presentation to DoIT CIO’s Office relating to PKI technical findings and costs 2003 – Present Pilot CA service made available to selective applications September 2000 Created PKILab with CS and others 2000 2001 IAIMS Secure Email Pilot 2002 Participated in Federal Bridge Pilot Project Fall 2003 CA server installed in production Summer 2004 Campus Requirements Gathering and RFI Sept. 2005 End user cert Deployment

PKI infrastructure The U.W.-Madison PKI is co-managed Time to implement Cost to implement Off site key backup The Equifax Secure Ebusiness CA1 Ability to migrate easily to in house solution

How the technology is being used Faculty – Staff – Students 120 “Early Adopters” Cryptographic USB devices Windows and Macintosh Digitally sign files and email Encrypt email and attachments Outlook, Outlook Express, Thunderbird and Mail.app

The look of UW-Madison digital certificiates

Case Examples UW-Madison Survey Center University Health Services Division of Information Technology Social Sciences Various Help Desks across campus

Current challenges Decentralized IT environment Cost Reaching critical mass Education Scaling User management and CRLs

The cost of not doing PKI University of California at Berkeley Stanford University University of Tennessee George Mason University Qualcomm

On the horizon Proposed digital signing of mass emails Proposed authentication to “high value” workstations and servers Proposed SSL certificates Convergence of other authentication technologies Digital signing as a replacement for ink signatures?

Critical success factors Transparency to the end users Ease of administration A clear roadmap and menu of service offerings Organizational awareness and education Top down management support and awareness of the complexity related to PKI policy A willingness to understand that rolling out a PKI is an iterative process of continuous improvement

Summary UW-Madison went live with PKI in September, 2005 Macintosh and Windows Email and file encryption and signing PKI as a technology suffers in general from several implementation challenges Running a successful PKI is an iterative process with some degree of fluidity Benefits of implementing a PKI far outweigh the risks of not having a PKI
