Insights from the 2nd PKI Workshop at CERN: Challenges and Progress in Public Key Infrastructure

DESCRIPTION

On June 12, 2003, the 2nd PKI Workshop convened at CERN, bringing together 121 participants with decades of research in Public Key Infrastructure (PKI). The event featured a program committee comprising experts from leading organizations such as NIH, AT&T Labs, and NIST. Discussions highlighted challenges in consumer PKI, including user enrollment failures and the complexities of managing revoked keys. The need for improved security interfaces and budget considerations for security tasks were emphasized. Published proceedings and papers are available online, offering detailed insights into the workshop's findings.

  3. Some Random Info • 121 participants -- 27 years of research into PKI issues • All problems have been solved • Program Committee: Peter Alterman NIH Matt Blaze AT&T Labs Research Bill Burr NIST Yassir Elley Sun Microsystems Carl Ellison(chair) Intel Stephen Farrell Baltimore Technologies Richard Guida Johnson & Johnson Peter Honeyman University of Michigan Ken Klingenstein University of Colorado Neal McBurnett Internet2 Clifford Neuman USC Eric Norman University of Wisconsin Tim Polk NIST Ravi Sandhu George Mason University Krishna Sankar Cisco Systems Frank Siebenlist Argonne National Laboratory Notes on 2nd PKI Workshop

  4. Consumer PKI • Alma Whitten (Why Johnny Can’t Encrypt) • Security is weird – Not like normal s/w Explore safely, undo errors, define goals (tell when done), recognize success • Need for research in interface for security • Important to include security tasks well in advance so time is budgeted properly Notes on 2nd PKI Workshop

  5. Canadian PKI • Credential repository • Similar to VSC • Passes back long term credential • Just a little scary Notes on 2nd PKI Workshop

  6. Random Comments • IE • 34 ways to go wrong when a user gets a cert • Very easy to end up with passphrase-less private keys • Enrollments failed in > 60% of the cases • Challenge for PGP email is: can’t change server, client or user • After 27 years, still haven’t solved the problem of how to deal with revoked and expired keys with respect to long term documents • Lots of interest in online repositories of various flavors • Discussion of proof of possession of private key Notes on 2nd PKI Workshop
