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

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 [1] https://raw.githubusercontent.com/google/psp/main/doc/PSP_Arch_Spec.pdf https://raw.githubusercontent.com/google/psp/main/doc/PSP_Ar...

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 https://en.wikipedia.org/wiki/PSP

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

    It should be exactly that for exactly that reason

  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://dl.acm.org/doi/10.1145/3708821.3710829 https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp4425.pdf https://csrc.nist.gov/CSRC/media/projects/cryptographic-modu... https://github.com/opencomputeproject/OCP-NET-Falcon https://github.com/opencomputeproject/OCP-NET-Falcon

      Good sleuthing. What a weird name, I wonder where it came from. The nursery rhyme somehow?
