Why would Google have encryption for Playstation Portable?
reactordev•4mo ago
Why would you associate Sony with Google?
homarp•4mo ago
psp =psp security protocol = PlayStation Portable security protocol

hence the question

kasabali•4mo ago
Lol, I've decided to look up and saw Wikipedia have 8 entries under computing for PSP acronym, none of them are Google's protocol :D

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

pkulak•4mo ago
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
mobilemidget•4mo ago
Should the acronym not be 'PSPSP'? Or that sounds too much like luring a cat?
c45y•4mo ago
It should be exactly that for exactly that reason
IshKebab•4mo ago
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.

Polizeiposaune•4mo ago
It appears to be referred to as the "Paddywhack Security Protocol" in some documents:

IshKebab•4mo ago
Good sleuthing. What a weird name, I wonder where it came from. The nursery rhyme somehow?
Veserv•4mo ago
While PSP seems like a reasonable protocol on its own, it is such a prime example of the left hand not knowing what the right is doing.

QUIC (over UDP) also requires encryption at its protocol layer in addition to encoding a encryption context identifier that is comparable, but non-compatible with the PSP header. So, a implementation that properly conforms to both standards would double encrypt the same data and send redundant headers/identifiers with no added security.

They could relatively easily restructure QUIC and PSP to be fully compatible, letting PSP do connection identification and encryption and then layering QUIC framing on top. But no. What a mess.
