I'm new to this process. I'm now reviewing RFC2026 and I see that I should not have referenced a "draft". Pardon me for that mistake. > The root of the trust could be a "Bridge" certification authority as defined > in 1.4.4 within draft-ietf-pkix-certpathbuild-03.txt. > Each TLD would be a "Principal" Certification Authority. > The draft is found at www.ietf.org/internet-drafts/draft-ietf-pkix-certpathbuild-03.txt > NOTE: the draft expires this month. Let me change the reference to: Bridge Certification Authorities: Connecting B2B Public Key Infrastructures by William T. Polk and Nelson E. Hastings for National Institute of Standards and Technology. This document can be found at: http ://csrc.nist.gov/pki/documents/B2B-article.pdf The "Bridge" and "Principal" explanations are virtually the same in both documents.
