                    Enrollment over Secure Transport
                         draft-ietf-pkix-est-00

Abstract

   This document profiles certificate enrollment for clients using
   Certificate Management over CMS (CMC) messages over a secure
   transport.  This profile, called Enrollment over Secure Transport
   (EST), describes a simple yet functional certificate management
   protocol targeting simple Public Key Infrastructure clients that need
   to acquire client certificate(s) and associated Certification
   Authority (CA) certificate(s).
