10 Path Matching Algorithm: Initialization One Develop certificate certification path Develop a list of (certpath-subject 0 ) (certpath- issuer 1, certpath-subject 1 ) (certpath-issuer 2, certpath-subject 2 ) etc., where certpath- subject 0 is the trust anchor DN and item (certpath-issuer i, certpath-subject i ) is the issuer and subject DNs from the i th certificate Delete all entries i, where certpath-issuer i = certpath-subject i –Get rid of self-issued certificates Renumber the entries to 1 through N cert
