Abstract

   A Strong Internet Name is a DNS name that contains a cryptographic
   binding to a security policy governing interpretation of the name.
   This document describes the use of Strong Internet Names formed using
   a Uniform Data Fingerprint of a PKIX trust root and outlines the
   additional capabilities that might be supported in a purpose written
   policy language.

1.  Introduction

   This document is written as a submission to the IAB workshop on
   Explicit Internet Naming Systems.  The proposal described here is a
   mechanism that allows a security policy and cryptographic root of
   trust to be introduced into any Internet identifier scheme that
   includes a DNS name without introducing new syntax.

   Strong Internet Names (SINs) bring together concepts introduced in
   the use of Strong Names introduced in the .Net security framework,
   fingerprints as used in OpenPGP and security policy description.

   Incorporating a fingerprint of a root of trust into an identifier
   produces an identifier whose interpretation is objective and does not
   depend on subjective assumptions as to whether a root of trust is
   trustworthy or not.

   Since the SIN only includes the fingerprint of the root of trust,
   rather than the root of trust itself, the process of interpretation
   will of course require a means of retrieving the additional
   information.
