7.1.  Digital Signature of Headers

   It is most desirable that group control messages (7.2) in particular
   be authenticated by incorporating them within some digital signature
   scheme that encompasses other headers closely associated with them
   (including at least the Approved-, Message-ID- and Date-headers). At
   the time of writing, this is usually done by means of a protocol
   known as "PGPverify" ([PGPVERIFY]), and continued usage of this is
   encouraged at least as an interim measure.

   However, PGPverify is not considered suitable for standardization in
   its present form, for various technical reasons. It is therefore
   expected that an early extension to this standard will provide a
   robust and general purpose digital authentication mechanism with
   applicability to all situations requiring protection against
   malicious use of, or interference with, headers.  That extension
   would also address other Netnews security issues.
