          Dynamic Symmetric Key Provisioning Protocol (DSKPP)

Abstract

   The Dynamic Symmetric Key Provisioning Protocol (DSKPP) is a client-
   server protocol for initialization (and configuration) of symmetric
   keys to locally and remotely accessible cryptographic modules.  The
   protocol can be run with or without private key capabilities in the
   cryptographic modules and with or without an established public key
   infrastructure.

   Two variations of the protocol support multiple usage scenarios.
   With the four-pass variant, keys are mutually generated by the
   provisioning server and cryptographic module; provisioned keys are
   not transferred over-the-wire or over-the-air.  The two-pass variant
   enables secure and efficient download and installation of pre-
   generated symmetric keys to a cryptographic module.
