For anyone else who's wondering what PSP is, from the Google spec[1]:

  The PSP Security Protocol (PSP) is a security protocol created by Google for encryption in
  transit. PSP uses several of the concepts from IPsec ESP to provide an encryption
  encapsulation layer on-top of IP that is streamlined and custom-built to address the
  requirements of large-scale data centers.
So "PSP" really is a recursive acronym for "PSP Security Protocol". eyeroll

Why would Google have encryption for Playstation Portable?
