Weaving a Web of Trust
Rohit Khare, UC Irvine, firstname.lastname@example.org, www.ics.uci.edu/~rohit
As once-proprietary mission-specific information systems migrate onto
the Web, traditional security analysis cannot sufficiently protect each
subsystem atomically. The Web encourages open, decentralized systems
that span multiple administrative domains. Trust Management is an emerging
framework for decentralizing security decisions that helps developers and
others in asking "why" trust is granted rather than immediately focusing
on "how" cryptography can enforce it. This talk introduces the fundamental
principles, principals, and policies of Trust Management, as well as Web-
specific pragmatic issues. [This work was originally presented in the
World Wide Web Journal, First Monday, and the National Research Council
Computer Science and Telecommunication Board's Information Systems
Trustworthiness committee. See http://www.cs.caltech.edu/~adam/papers/
Biography: Rohit Khare joined the Ph.D. program in computer science at
the University of California, Irvine in Fall 1997, after serving as a
member of the MCI Internet Architecture staff. He was previously on the
technical staff of the World Wide Web Consortium at MIT, where he focused
on security and electronic commerce issues. He has been involved in the
development of cryptographic software tools and Web-related standards
development. Rohit received a B.S. in Engineering and Applied Science
and in Economics from the California Institute of Technology in 1995.
Validating the Net: an Internet-scale Certificate Validation Service
Ambarish Malpani, Founder and Lead Architect, ValiCert,
ValiCert's universal approach addresses potentially debilitating
performance and compatibility problems related to certificate validation.
A key component of the ValiCert solution is its high performance
Certificate Revocation Tree (CRT) technology, which allows validation
of digital certificates without downloading the entire global revocation
list. This approach scales easily to accommodate hundreds of billions of
certificates without creating an undue burden on the client requesting
validation information. The result: vastly improved performance compared
to earlier mechanisms, such as Certificate Revocation Lists (CRLs).
Biography: Ambarish Malpani is ValiCert's first employee and joined the
company with over ten years of industry experience as a systems designer
and architect. Most recently, Ambarish was a consultant specializing in
cryptography and Internet applications. Ambarish holds an M.S. degree
from the University of California at Santa Barbara and a B.S. degree from
the Indian Institute of Technology, Bombay.
