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

Oh good. They made up an acronym, yet managed to find one of the ones already in the heaviest (computing) use: https://en.wikipedia.org/wiki/PSP

Not only that but since they chose a super original and totally not cringeworthy recursive acronym the first letter could have been literally anything.

Ok in fairness it was probably originally something like Paul's Security Protocol and they felt that that wasn't professional enough or something.

		It appears to be referred to as the "Paddywhack Security Protocol" in some documents: https://dl.acm.org/doi/10.1145/3708821.3710829 https://csrc.nist.gov/CSRC/media/projects/cryptographic-modu... https://github.com/opencomputeproject/OCP-NET-Falcon

Should the acronym not be 'PSPSP'? Or that sounds too much like luring a cat?

		It should be exactly that for exactly that reason
