Technical Summary

   Public-key certificates need to be revoked when they are compromised,
   that is, when the associated private key is exposed to an
   unauthorized entity.  However the revocation process is often
   unreliable.  An alternative to revocation is issuing a sequence of
   certificates, each with a short validity period, and terminating this
   sequence upon compromise.  This memo proposes an ACME extension to
   enable the issuance of short-term and automatically renewed (STAR)
   X.509 certificates.

** The MAMI implementation of this draft is being integrated with the OSM orchestrator [0] for NFV workloads;
** GSMA is considering ACME STAR as one of the reference solutions for handling encrypted content in CDNI (see also [1]);
** There has been discussion related to the use of short-term certs for non-web use cases (see [2]), for example in the ANIMA control plane [3].
** The CDNI working group plans to use this work
