This document updates RFC 5280 to replace the algorithm for X.509
policy validation with an equivalent, more efficient algorithm. The
original algorithm built a structure that scaled exponentially in the
worst case, leaving implementations vulnerable to denial-of-service
attacks.
This document is a product of the Limited Additional Mechanisms for PKIX and
SMIME Working Group of the IETF.
This is now a Proposed Standard.
