                 Simple Certificate Enrollment Protocol
                          draft-nourse-scep-23

Abstract

   This document specifies the Simple Certificate Enrollment Protocol
   (SCEP), a Public Key Infrastructure (PKI) communication protocol
   which leverages existing technology by using PKCS#7 and PKCS#10 over
   HTTP.  SCEP is the evolution of the enrollment protocol developed by
   VeriSign, Inc. for Cisco Systems, Inc. It now enjoys wide support in
   both client and a Certification Authority implementations.
