 o The CA hierarchy is traversed to the root CA
 o You trust/believe the root CA
 o The CAs maintain up-to-date CRLs and they are checked
 o etc.

Certs *may* be more secure and robust.  See 
http://www.counterpane.com/pki-risks.pdf and the IETF PKIX mailing 
list, etc. for "mitigating factors."  When used and managed 
inappropriately, it is very easy to get a false sense of security from 
PKIs . . . It's not easy to use certs securely.  |-}
