Abstract

   The EST (Enrollment over Secure Transport) protocol defined a Well-
   Known URI (Uniform Resource Identifier): /.well-known/est along with
   a number of other path components that clients use for PKI (Public
   Key Infrastructure) services, namely certificate enrollment (e.g.,
   /simpleenroll).  This document defines a number of other PKI services
   as additional path components, specifically firmware and trust
   anchors as well as symmetric, asymmetric, and encrypted keys.  This
   document also specifies the PAL (Package Availability List), which is
   an XML (Extensible Markup Language) file or JSON (JavaScript Object
   Notation) object that clients use to retrieve packages available and
   authorized for them.  This document extends the EST server path
   components to provide these additional services.
